'Reform' in the Bible

and Peter said unto them, 'Reform, and be baptized each of you on the name of Jesus Christ, to remission of sins, and ye shall receive the gift of the Holy Spirit,

reform ye, therefore, and turn back, for your sins being blotted out, that times of refreshing may come from the presence of the Lord,

reform, therefore, from this thy wickedness, and beseech God, if then the purpose of thy heart may be forgiven thee,

the times, indeed, therefore, of the ignorance God having overlooked, doth now command all men everywhere to reform,

but to those in Damascus first, and to those in Jerusalem, to all the region also of Judea, and to the nations, I was preaching to reform, and to turn back unto God, doing works worthy of reformation;
