'Regret' in the Bible

and saying, “The [appointed period of] time is fulfilled, and the kingdom of God is at hand; repent [change your inner self—your old way of thinking, regret past sins, live your life in a way that proves repentance; seek God’s purpose for your life] and believe [with a deep, abiding trust] in the good news [regarding salvation].”

For even though I did grieve you with my letter, I do not regret it [now]; though I did regret it —for I see that the letter hurt you, though only for a little while—

For [godly] sorrow that is in accord with the will of God produces a repentance without regret, leading to salvation; but worldly sorrow [the hopeless sorrow of those who do not believe] produces death.

(for those Levites who formerly became priests [received their office] without [its being confirmed by the taking of] an oath, but this One [was designated] with an oath through the One who said to Him,“The Lord has swornAnd will not change His mind or regret it,‘You (Christ) are a Priest forever’”).

People were [severely] burned by the great heat; and they reviled the name of God who has power over these plagues, but they did not repent [of their sin] and glorify Him.
