John Gill Commentary Lamentations 5:6

"We have given the hand to the Egyptians, And to the Assyrians, to be satisfied with bread." — Lamentations 5:6 (ASV)

We have given our hand [to] the Egyptians
Either by way of supplication, to beg bread of them; or by way of covenant and agreement; or to testify subjection to them, in order to be supplied with food: many of the Jews went into Egypt upon the taking of the city, (Jeremiah 43:5–7) ; [and to] the Assyrians, to be satisfied with bread ;
among whom many of the captives were dispersed; since from hence they are said to be returned, as well as from Egypt, (Isaiah 11:16) .
