And [recall, O People of the Scripture], when Allāh took the covenant of the prophets, [saying], "Whatever I give you of the Scripture and wisdom and then there comes to you a messenger confirming what is with you, you [must] believe in him and support him." [Allāh] said, "Have you acknowledged and taken upon that My commitment?" They said, "We have acknowledged it." He said, "Then bear witness, and I am with you among the witnesses."

When Allah made the prophets enter into a covenant: (saying) “If I give you a book and wisdom, then comes to you a messenger verifying what is with you, you shall have to believe in him, and you shall have to support him.” He said, “Do you affirm and accept my covenant in this respect?” They said, “We affirm.” He said, “Then, bear witness, and I am with you among the witnesses.”
