B'resheet 24:1-3 Now Avraham was old, advanced in age; and the L-RD had blessed Avraham in every way. And Avraham said to his servant, the oldest of his household, who had charge of all that he owned, "Please place your hand under my thigh, and I will make you swear by the L-RD, the G-d of heaven and the G-d of earth, that you shall not take a wife for my son from the daughters of the Canaanites, among whom I live,
The Canaanites did not know the one true G-d and Avraham wanted his family to be divided from them.
The corresponding letter to this chapter is Beit - house, duality as in husband and wife; also division between good and evil, etc.
Here we see Avraham searching for a wife for his son. This is symbolic of HaShem searching for a bride for His son. The servant in this story symbolizes Ruach HaKodesh (the Holy Spirit). Ruach HaKodesh goes out in search of a bride for Yeshua.
under my thigh - na yadecha in Hebrew. The numeric value of the two words na yeadecha is 85. The sages say that Avraham asked Eliezer to swear by his b'rit milah (circumcision). The numerical value of milah is 85. The circumcision is a sign of the covenant between G-d and Avraham, therefore the servant had to lay his hand on the sign of that covenant to swear His allegiance to Avraham and G-d.
B'resheet 24:4-9 but you shall go to my country and to my relatives, and take a wife for my son Yitz'chak. " And the servant said to him, "Suppose the woman will not be willing to follow me to this land; should I take your son back to the land from where you came?" Then Avraham said to him, "Beware lest you take my son back there! "The L-RD, the G-d of heaven, who took me from my father's house and from the land of my birth, and who spoke to me, and who swore to me, saying, 'To your descendants I will give this land,' He will send His angel before you, and you will take a wife for my son from there. But if the woman is not willing to follow you, then you will be free from this my oath; only do not take my son back there." So the servant placed his hand under the thigh of Avraham his master, and swore to him concerning this matter.
Avraham did not want Yitz'chak to go back to his former homeland even for a visit. His place was in the land G-d had given him.
B'resheet 24:10-14 Then the servant took ten camels from the camels of his master, and set out with a variety of good things of his master's in his hand; and he arose, and went to Mesopotamia, to the city of Nahor. And he made the camels kneel down outside the city by the well of water at evening time, the time when women go out to draw water. And he said, "O L-RD, the G-d of my master Avraham, please grant me success today, and show loving kindness to my master Avraham. Look, I am standing by the spring, and the daughters of the men of the city are coming out to draw water; now may it be that the girl to whom I say,' Please let down your jar so that I may drink,' and who answers,' Drink, and I will water your camels also';-- may she be the one whom You have appointed for Your servant Yitz'chak; and by this I shall know that You have shown loving kindness to my master."
The job of watering a camel is not a small job. Watering 10 camels is a very big job and not many women would be volunteering for this job.
B'resheet 24:15-19 And it came about before he had finished speaking, that behold, Rivkah who was born to Bethuel the son of Milcah, the wife of Avraham's brother Nahor, came out with her jar on her shoulder. And the girl was very beautiful, a virgin, and no man had had relations with her; and she went down to the spring and filled her jar, and came up. Then the servant ran to meet her, and said, "Please let me drink a little water from your jar." And she said, "Drink, my lord"; and she quickly lowered her jar to her hand, and gave him a drink. Now when she had finished giving him a drink, she said, "I will draw also for your camels until they have finished drinking."
G-d immediately answers the servant's prayers. His prayer was very specific and G-d answered it to the smallest detail.
We learn that: Rivkah was beautiful, a virgin, hospitable, and a hard worker.
B'resheet 24:20-27 So she quickly emptied her jar into the trough, and ran back to the well to draw, and she drew for all his camels. Meanwhile, the man was gazing at her in silence, to know whether the L-RD had made his journey successful or not. Then it came about, when the camels had finished drinking, that the man took a gold ring weighing a half-shekel and two bracelets for her wrists weighing ten shekels in gold, and said, "Whose daughter are you? Please tell me, is there room for us to lodge in your father's house?" And she said to him, "I am the daughter of Bethuel, the son of Milcah, whom she bore to Nahor." Again she said to him, "We have plenty of both straw and feed, and room to lodge in." Then the man bowed low and worshiped the L-RD. And he said, "Blessed be the L-RD, the G-d of my master Avraham, who has not forsaken His loving kindness and His truth toward my master; as for me, the L-RD has guided me in the way to the house of my master's brothers."
bowed low and worshiped the L-RD - The servant immediately remembered to thank G-d for His guidance and direction.
B'resheet 24:28-33 Then the girl ran and told her mother's household about these things. Now Rivkah had a brother whose name was Laban; and Laban ran outside to the man at the spring. And it came about that when he saw the ring, and the bracelets on his sister's wrists, and when he heard the words of Rivkah his sister, saying, "This is what the man said to me," he went to the man; and behold, he was standing by the camels at the spring. And he said, "Come in, blessed of the L-RD! Why do you stand outside since I have prepared the house, and a place for the camels?" So the man entered the house. Then Laban unloaded the camels, and he gave straw and feed to the camels, and water to wash his feet and the feet of the men who were with him. But when food was set before him to eat, he said, "I will not eat until I have told my business." And he said, "Speak on."
This points us to the future and the picture of Yeshua with the woman at the well. This woman and all who trust in Him are future brides of Yeshua. This woman also replies the same way stating:
John 4:28-30 So the woman left her water pot, and went into the city, and said to the men, "Come, see a man who told me all the things that I have done; this is not the Messiah, is it?"
In contrast, this women was not a virgin but had had five husbands but was still offered to become the bride of the Father's Son like we all are if we trust.
John 4:15-19 The woman said to Him, "Sir, give me this water, so I will not be thirsty, nor come all the way here to draw." He said to her, "Go, call your husband, and come here." The woman answered and said, "I have no husband." Yeshua said to her, "You have well said, 'I have no husband'; for you have had five husbands, and the one whom you now have is not your husband; this you have said truly. " The woman said to Him, "Sir, I perceive that You are a prophet.
Some of the Samaritans may have had mixture of other races but they where still brothers and Jewish in similar manner to Avraham's brothers. We all may not even be Jewish physically at all but we all can become Jewish spiritually by coming to know the Jewish Messiah Yeshua. The Father came to bless and wanted His Son to be betrothed to people of all nations in contrast to Avraham who wanted to keep his son from the Canaanites.
Luke 9:51-56 And it came about, when the days were approaching for His ascension, that He resolutely set His face to go to Jerusalem; and He sent messengers on ahead of Him. And they went, and entered a village of the Samaritans, to make arrangements for Him. And they did not receive Him, because He was journeying with His face toward Jerusalem. And when His disciples James and John saw this, they said, "L-rd, do You want us to command fire to come down from heaven and consume them?" But He turned and rebuked them, and said, "You do not know what kind of spirit you are of; for the Son of Man did not come to destroy men's lives, but to save them.
Yeshua brings peace to all with the Father for those that trust in Him.
John 12:44-50 And Yeshua cried out and said, "He who believes in Me does not believe in Me, but in Him who sent Me. "And he who beholds Me beholds the One who sent Me. "I have come as light into the world, that everyone who believes in Me may not remain in darkness. "And if anyone hears My sayings, and does not keep them, I do not judge him; for I did not come to judge the world, but to save the world. "He who rejects Me, and does not receive My sayings, has one who judges him; the word I spoke is what will judge him at the last day. "For I did not speak on My own initiative, but the Father Himself who sent Me has given Me commandment, what to say, and what to speak. "And I know that His commandment is eternal life; therefore the things I speak, I speak just as the Father has told Me."
