O Foolish Galatians

Gal 3:1 O foolish Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you?
Gal 3:2 This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith?
Gal 3:3 Are ye so foolish? having begun in the Spirit, are ye now made perfect by the flesh?
Gal 3:4 Have ye suffered so many things in vain? if it be yet in vain.
Gal 3:5 He therefore that ministereth to you the Spirit, and worketh miracles among you, doeth he it by the works of the law, or by the hearing of faith?
