Forgive us as we forgive others

In Psalm 25, we read:

⁶ Yahweh, remember your tender mercies and your loving kindness, for they are from old times. ⁷ Don’t remember the sins of my youth, nor my transgressions. Remember me according to your loving kindness, for your goodness’ sake, Yahweh.

What we ask of God, God asks of us, so we are to think of others in loving kindness. We are to put aside the transgressions people may have done in the past (and the Lord’s Prayer points out we must forgive if we want God to forgive us.).

Who or what do each of us need to forgive?
