Numbers 24:20

Timna was a concubine of Esau’s son Eliphaz, and she bore Amalek to Eliphaz. These are the sons of Esau’s wife Adah.

Then Amalek came and fought against Israel at Rephidim.

“Water will flow from his buckets, And his seed will be by many waters, And his king shall be lifted up higher than Agag, And his kingdom shall be exalted.

“But ships shall come from the coast of Kittim, And they shall afflict Asshur and will afflict Eber; So they also will come to destruction.”

“Thus says Yahweh of hosts, ‘I will punish Amalek for what he did to Israel, how he set himself against him on the way while he was coming up from Egypt.

‘Now go and strike Amalek and devote to destruction all that he has, and do not spare him; but put to death both man and woman, infant and nursing baby, ox and sheep, camel and donkey.’”
