and also Mizpah, for he said, “May the Lord watch between you and me when we are out of each other’s sight.

Come, let’s drink deeply of lovemaking until morning.Let’s feast on each other’s love!

I will make them eat the flesh of their sons and their daughters, and they will eat each other’s flesh in the siege and distress that their enemies, those who want to take their life, inflict on them.

Then I said, “I will no longer shepherd you. Let what is dying die, and let what is going astray go astray; let the rest devour each other’s flesh.”

that is, to be mutually encouraged by each other’s faith, both yours and mine.
