Exodus 17:8

ויבא עמלק THEN CAME AMALEK — Scripture places this section immediately after this preceding verse (they said, “Is the Lord among us or not?”) to imply, “I am ever among you and ready at hand for every thing you may need, and yet you say, “Is the Lord among us or not?” By your lives, I swear that the hound (Amalek) shall come and bite you, and you will cry for Me and then you will know where I am!” A parable: it may be compared to a man who carried his son upon his shoulder, and went out on a journey. The son saw an article and said, “Father, pick up that thing and give it to me”. He gave it to him, and so a second time and so also a third time. They met a certain man to whom the son said, “Have you seen my father anywhere?” Whereupon his father said to him, “Don’t you know where I am?” — He, therefore, cast him off from himself and a hound came and bit him (Midrash Tanchuma, Yitro 3).

Then came ῾Amaleq, and fought with Yisra᾽el in Refidim.
