'Alliances' in the Bible

“You were wearied by the length of your road,Yet you did not say, ‘It is no use.’You found renewed strength,Therefore you did not grow weak.

“This is your destiny, the portion [of judgment] measured to youFrom Me,” says the Lord,“Because you have forgotten MeAnd trusted in [pagan] lies [the counterfeit gods, and the pretense of alliance].”

Do not be unequally bound together with unbelievers [do not make mismatched alliances with them, inconsistent with your faith]. For what partnership can righteousness have with lawlessness? Or what fellowship can light have with darkness?
