Paul wrote to the Galatian congregations that if they encountered a person who had failed, whether intentionally or just through weakness, by implication of the word used to describe the error, the spiritual among them should restore the person, being humbled by their own weaknesses and iniquities:

(Galatians 6:1 Holman Christian Standard Bible®©)
The word translated “restore” in that place is also used in a blessing near the end of Hebrews. There, it is translated, “equip,” (or “perfect” according to footnote)”: Now may the God of peace, who brought up from the dead our Lord Jesus—the great Shepherd of the sheep—with the blood of the everlasting covenant, equip [perfect] you with all that is good to do His will, working in us what is pleasing in His sight, through Jesus Christ, to whom be glory forever and ever. Amen.
