The corresponding letter to this chapter is Zayin – focal point of sustenance and struggle.
Sh’mu’el Bet 7:1-3 Now it came about when the king lived in his house, and the L-RD had given him rest on every side from all his enemies, that the king said to Natan the prophet, "See now, I dwell in a house of cedar, but the ark of G-d dwells within tent curtains." And Natan said to the king, "Go, do all that is in your mind, for the L-RD is with you."
Now David had a good idea. It was an honorable idea. When he told Natan his idea Natan thought it was a good idea too. Natan was a prophet and he gave David G-d’s blessing to move forward with the construction of a temple. The problem with David’s plan was neither he nor Natan had consulted G-d to see if it was what he wanted.
Sh’mu’el Bet 7:4-7 But it came about in the same night that the word of the L-RD came to Natan, saying, "Go and say to My servant David, 'Thus says the L-RD," Are you the one who should build Me a house to dwell in? "For I have not dwelt in a house since the day I brought up the sons of Israel from Egypt, even to this day; but I have been moving about in a tent, even in a tabernacle. Wherever I have gone with all the sons of Israel, did I speak a word with one of the tribes of Israel, which I commanded to shepherd My people Israel, saying, 'Why have you not built Me a house of cedar?'"'
Are you the one who should build Me a house - G-d speaks to Natan and gives him a message for David. First He basically asks him if he is so sure he is the one to build a temple.
Sh’mu’el Bet 7:8-13 "Now therefore, thus you shall say to My servant David, 'Thus says the L-RD of hosts," I took you from the pasture, from following the sheep, that you should be ruler over My people Israel. And I have been with you wherever you have gone and have cut off all your enemies from before you; and I will make you a great name, like the names of the great men who are on the earth. I will also appoint a place for My people Israel and will plant them, that they may live in their own place and not be disturbed again, nor will the wicked afflict them any more as formerly, even from the day that I commanded judges to be over My people Israel; and I will give you rest from all your enemies. The L-RD also declares to you that the L-RD will make a house for you. When your days are complete and you lie down with your fathers, I will set up your seed after you, who will come forth from you, and I will establish his kingdom. He shall build a house for My name, and I will establish the throne of his kingdom forever.
G-d acknowledges that he put David into power and has vanquished his enemies. David’s son, Shlomo, will be the one to build the temple.
Divrei-Hayamim Alef (1 Chronicles 22:8) But the word of the LORD came to me, saying, 'You have shed much blood, and have waged great wars; you shall not build a house to My name, because you have shed so much blood on the earth before Me.
The throne of his kingdom forever – This is a reference to the throne of the Mashiach, Yeshua.
Yesha’yahu (Isaiah) 9:6-7 For unto us a Child is born, Unto us a Son is given; And the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty G-d, Everlasting Father, Prince of Peace. Of the increase of His government and peace There will be no end, Upon the throne of David and over His kingdom, To order it and establish it with judgment and justice From that time forward, even forever. The zeal of the L-RD of hosts will perform this.
Back to the promise:
Sh’mu’el Bet 7:14 I will be a father to him and he will be a son to Me; when he commits iniquity, I will correct him with the rod of men and the strokes of the sons of men,
“When he commits iniquity” concerns the intermediary seed (Shlomo) until the ultimate Seed of David who had no sin.
Sh’mu’el Bet 7:15-17 but My loving kindness shall not depart from him, as I took it away from Sha’ul, whom I removed from before you. And your house and your kingdom shall endure before Me forever; your throne shall be established forever."' " In accordance with all these words and all this vision, so Natan spoke to David.
This is an unconditional covenant know as the Davidic covenant. It is a promise that a son of David will sit on the throne of Israel forever. This son is none other than Yeshua HaMashiach.
Sh’mu’el Bet 7: 18-29 Then David the king went in and sat before the L-RD, and he said, "Who am I, O L-rd G-D, and what is my house, that You have brought me this far? "And yet this was insignificant in your eyes, O L-rd G-D, for You have spoken also of the house of your servant concerning the distant future. And this is the custom of man, O L-rd G-D. And again what more can David say to Thee? For You know your servant, O L-rd G-D! "For the sake of your word, and according to your own heart, You have done all this greatness to let your servant know. For this reason You are great, O L-rd G-D; for there is none like You, and there is no G-d besides You, according to all that we have heard with our ears. And what one nation on the earth is like your people Israel, whom G-d went to redeem for Himself as a people and to make a name for Himself, and to do a great thing for you and awesome things for your land, before your people whom You have redeemed for yourself from Egypt, from nations and their gods? "For You have established for yourself your people Israel as your own people forever, and You, O L-RD, have become their G-d. Now therefore, O L-RD G-d, the word that You have spoken concerning your servant and his house, confirm it forever, and do as You have spoken, that your name may be magnified forever, by saying,' The L-RD of hosts is G-d over Israel'; and may the house of your servant David be established before You. For You, O L-RD of hosts, the G-d of Israel, has made a revelation to your servant, saying, 'I will build you a house'; therefore your servant has found courage to pray this prayer to You. And now, O L-rd G-D, You are G-d, and your words are truth, and You have promised this good thing to your servant. Now therefore, may it please you to bless the house of your servant, that it may continue forever before You. For you, O L-rd G-D, have spoken; and with your blessing may the house of your servant be blessed forever."
Sat before the L-RD – This refers to David going and sitting before the “ark of the covenant”.
Who am I, O L-rd G-D, and what is my house, that You have brought me this far? – David shows humility and not arrogance with this new revelation. He understands that he is to be the ancestor of the Mashiach and is honored.
