Gill's Exposition of the Entire BibleAnd I will cut off witchcrafts out of thine hand,.... Such as were formerly practised among the Jews, though forbidden them, and in mystical Babylon, or the antichristian church, whose sorceries are mentioned, Revelation 9:21; but nothing of this kind will be found in the Christian church, consisting of Jews and Gentiles, in the latter day; all unlawful arts, cheating and juggling in religious matters, will cease, and be no more: and thou shalt have no more soothsayers; or diviners, that cast a mist over people's eyes, and deceived them with false appearances of things; that pretended to know times and seasons, when it was or was not a good day to go abroad, or to make merchandise; that judged by the clouds, and by the position of the heavens, what would come to pass hereafter; and though such sort of men were formerly indulged, connived at, and caressed among the Jews, they should be so no more; nor should they apply to such persons for advice and counsel; nor would they need it, nor should they use it; see Deuteronomy 18:10.

But to those who neglected or opposed this salvation, they would, as lions, cause terror, their doctrine condemning them.

In like manner shall we be assured of victory in our personal conflicts, as we simply depend upon the Lord our salvation, worship him, and serve him with diligence. |
