The Westminster Shorter Catechism (1648)

18 When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life.

37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?

38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.

12 Therefore also now, saith the LORD, turn ye even to me with all your heart, and with fasting, and with weeping, and with mourning:

22 Return, ye backsliding children, and I will heal your backslidings. Behold, we come unto thee; for thou art the LORD our God.

18 I have surely heard Ephraim bemoaning himself thus; Thou hast chastised me, and I was chastised, as a bullock unaccustomed to the yoke: turn thou me, and I shall be turned; for thou art the LORD my God.

19 Surely after that I was turned, I repented; and after that I was instructed, I smote upon my thigh: I was ashamed, yea, even confounded, because I did bear the reproach of my youth.

31 Then shall ye remember your own evil ways, and your doings that were not good, and shall loathe yourselves in your own sight for your iniquities and for your abominations.

11 For behold this selfsame thing, that ye sorrowed after a godly sort, what carefulness it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what vehement desire, yea, what zeal, yea, what revenge! In all things ye have approved yourselves to be clear in this matter.

16 Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil;

17 Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
