Isaiah 49:26

Amplified Bible

²⁶ 
“I will make those who oppress you consume their own flesh [in mutually destructive wars]
And they will become drunk with their own blood as with sweet wine;
And all ^[a]mankind will know [with a knowledge grounded in personal experience] that I, the Lord, am your Savior
And your Redeemer, the Mighty One of Jacob.”
