'Acceptable' in the Bible

Let the words of my mouth and the meditation of my heartBe acceptable and pleasing in Your sight,O Lord, my [firm, immovable] rock and my Redeemer.

My [only] sacrifice [acceptable] to God is a broken spirit;A broken and contrite heart [broken with sorrow for sin, thoroughly penitent], such, O God, You will not despise.

But as for me, my prayer is to You, O Lord, at an acceptable and opportune time;O God, in the greatness of Your favor and in the abundance of Your lovingkindness,Answer me with truth [that is, the faithfulness of Your salvation].
