Parallel
Psalms 56:5
Brenton's English Septuagint · Berean Standard Bible
and he has delivered my soul from the midst of [lions'] whelps: I lay down to sleep, [though] troubled. [As for] the sons of men, their teeth are arms and [missile] weapons, and their tongue a sharp sword.
57:4
My soul is among the lions; I lie down with ravenous beasts—with men whose teeth are spears and arrows, whose tongues are sharp swords.
