1 Kings 18:37

That thou hast turned their heart; that they may feel so powerful and sudden a change in their hearts, that they may know it is thy work, and the effect of thy grace to them, and in them. Or, when thou hast turned, &c., or, because thou, &c. So the particle vau is oft used; and the sense is, That they may know thee to be the true God, by the effects of thy Divine power, in converting their hearts, and that in so miraculous a way, and in answer to my prayers. Back again unto thee, from whom they have revolted.
