Joel 2:12

Therefore turn thou to thy God: keep mercy and judgment, and wait on thy God continually.

If thou wilt return, O Israel, saith the LORD, return unto me: and if thou wilt put away thine abominations out of my sight, then shalt thou not remove.

Come, and let us return unto the LORD: for he hath torn, and he will heal us; he hath smitten, and he will bind us up.

And they gathered together to Mizpeh, and drew water, and poured it out before the LORD, and fasted on that day, and said there, We have sinned against the LORD. And Samuel judged the children of Israel in Mizpeh.

O Israel, return unto the LORD thy God; for thou hast fallen by thine iniquity.

But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance.

And Samuel spake unto all the house of Israel, saying, If ye do return unto the LORD with all your hearts, then put away the strange gods and Ashtaroth from among you, and prepare your hearts unto the LORD, and serve him only: and he will deliver you out of the hand of the Philistines.

Then all the children of Israel, and all the people, went up, and came unto the house of God, and wept, and sat there before the LORD, and fasted that day until even, and offered burnt offerings and peace offerings before the LORD.

And in that day did the Lord GOD of hosts call to weeping, and to mourning, and to baldness, and to girding with sackcloth:

And to speak unto the priests which were in the house of the LORD of hosts, and to the prophets, saying, Should I weep in the fifth month, separating myself, as I have done these so many years?

Speak unto all the people of the land, and to the priests, saying, When ye fasted and mourned in the fifth and seventh month, even those seventy years, did ye at all fast unto me, even to me?
