Exodus 17:14-16

BBE(i) 14 And the Lord said to Moses, Make a record of this in a book, so that it may be kept in memory, and say it again in the ears of Joshua: that all memory of Amalek is to be completely uprooted from the earth. 15 Then Moses put up an altar and gave it the name of Yahweh-nissi: 16 For he said, The Lord has taken his oath that there will be war with Amalek from generation to generation.
