Exodus 17:13-16

LXX2012(i) 13 And Joshua routed Amalec and all his people with the slaughter of the sword. 14 And the Lord said to Moses, Write this for a memorial in a book, and speak [this] in the ears of Joshua; for I will utterly blot out the memorial of Amalec from under heaven. 15 And Moses built an altar to the Lord, and called the name of it, The Lord my Refuge. 16 For with a secret hand the Lord wages war upon Amalec to all generations.
