verse 10 - 20: David praised the Lord before the entire assembly:
O Lord God of our father Israel, you deserve praise forevermore!
O Lord, you are great, mighty, majestic, magnificent, glorious and sovereign over all the sky and earth! You have dominion and exalt yourself as the ruler of all. You are the source of wealth and honor, you rule over all. You possess strength and might to magnify and give strength to all. Now our God, we give thanks to you and praise your majestic name!
But who am I and who are my people, that we should be in a position to contribute this much? Indeed, everything comes from you, and we have simply given back to you what is yours. For we are resident foreigners and nomads in your presence, like all our ancestors; our days are like a shadow on the earth, without security.
O Lord our God, all this wealth, which we have collected to build a temple for you to honor your holy name, comes from you; it all belongs to you. I know, my God, that you examine thoughts and are pleased with integrity. With pure motives I contribute all this; and now I look with joy as your people who have gathered here contribute to you. O Lord God of our ancestors Abraham, Isaac, and Israel, maintain the motives of your people and keep them devoted to you. Make my son Solomon willing to obey your commands, rules, and regulations, and to complete building the palace for which I have made preparations.
David told the entire assembly: Praise the Lord your God ! So the entire assembly praised the Lord God of their ancestors, they bowed down and stretched out flat on the ground before the Lord and the king.
I Chronicles 28:19-20 David said: All of this I put in writing as the Lord directed me and gave me insight regarding the details of the blueprints. David said to his son Solomon: Be strong and brave! Do it! Don't be afraid and don't panic. For the Lord God, my God, is with you. He will not leave you or abandon you before all the work for the service of the Lord's temple is finished.
I Chronicles 17: 10- Moreover, I tell you that the Lord will build a house for you. ....I will set up one of your descendants after you, who shall be of our sons; and I will establish his kingdom. He shall build for Me a house, and I will establish his throne forever.
(I love the word play on the word house. David desires to build God a House and God turns it around and promised David that He would establish David's house/dynasty or lineage forever. Jesus Christ became that Son of David. Jesus Christ will rule forever. And now as our sons have sons and daughters, they depend on God's Word and principles found in the Word to raise their children with integrity, courage, and honor...establishing a house. Our houses of brick and mortar and sheetrock and paint and tile house the real house--the family that is our home. And we look to God for direction, purpose, with thankfulness in the blessing of healthy babies.)
