Thematic Bible: The israelites on the amalekites

Remember what Amalek did unto thee by the way when ye were come forth out of Egypt, how he met thee by the way and smote the hindmost of thee, even all that were feeble behind thee, when thou wast faint and weary and he did not fear God. Therefore it shall be when the LORD thy God has given thee rest from all thine enemies round about in the land which the LORD thy God gives thee for an inheritance to possess it that thou shalt blot out the remembrance of Amalek from under heaven; thou shalt not forget it.

And Samuel said unto Saul, The LORD sent me to anoint thee to be king over his people, over Israel; now, therefore, hearken thou unto the voice of the words of the LORD. Thus hath said the LORD of the hosts, I remember that which Amalek did to Israel, how he laid wait for him in the way when he came up from Egypt. Now go and smite Amalek and utterly destroy all that they have and spare him not, but slay both man and woman, infant and suckling, ox and sheep, camel and ass. read more.
