Exegesis:

mē kōluete “do not try to stop him” (An American Translation).

Translation:

He that is not against you is for you, or rendering the prepositions otherwise, ‘he that is not your adversary, he is your companion’ (Bahasa Indonesia, using two closely similar forms, lawan and kawan), ‘when a person does not oppose us, he helps us’ (Sundanese), ‘the man that does not oppose you, he is your partner’ (Sranan Tongo).
