Deuteronomy 32:34-36

34“Have I not kept this in reserve and sealed it in my vaults?

35It is mine to avenge; I will repay. In due time their foot will slip; their day of disaster is near and their doom rushes upon them.”

36The LORD will vindicate his people and relent concerning his servants when he sees their strength is gone and no one is left, slave or free. Or and they are without a ruler or leader
