1 Chronicles 28:1-5

(1) And David assembled all the princes of Israel, the princes of the tribes, and the captains of the companies that ministered to the king by course, and the captains over the thousands, and captains over the hundreds, and the stewards over all the substance and possession of the king, and of his sons, with the officers, and with the mighty men, and with all the valiant men, unto Jerusalem.
(2) Then David the king stood up upon his feet, and said, Hear me, my brethren, and my people: As for me, I had in mine heart to build an house of rest for the ark of the covenant of the LORD, and for the footstool of our God, and had made ready for the building:
(3) But God said unto me, Thou shalt not build an house for my name, because thou hast been a man of war, and hast shed blood.
(4) Howbeit the LORD God of Israel chose me before all the house of my father to be king over Israel for ever: for he hath chosen Judah to be the ruler; and of the house of Judah, the house of my father; and among the sons of my father he liked me to make me king over all Israel:
(5) And of all my sons, (for the LORD hath given me many sons,) he hath chosen Solomon my son to sit upon the throne of the kingdom of the LORD over Israel.

Exodus 17:8-16

(8) Then came Amalek, and fought with Israel in Rephidim.
(9) And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with the rod of God in mine hand.
(10) So Joshua did as Moses had said to him, and fought with Amalek: and Moses, Aaron, and Hur went up to the top of the hill.
(11) And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed.
(12) But Moses' hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun.
(13) And Joshua discomfited Amalek and his people with the edge of the sword.
(14) And the LORD said unto Moses, Write this for a memorial in a book, and rehearse it in the ears of Joshua: for I will utterly put out the remembrance of Amalek from under heaven.
(15) And Moses built an altar, and called the name of it Jehovahnissi:
(16) For he said, Because the LORD hath sworn that the LORD will have war with Amalek from generation to generation.
