Forsake
To leave or abandon. Famously used in the Old Testament in Deuteronomy 31:6: "Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you." And by Jesus in the New Testament on the cross in Matthew 27:46: "About three in the afternoon Jesus cried out in a loud voice, "Eli, Eli, [a] lema sabachthani?" (which means "My God, my God, why have you forsaken me?")."
