'Acceptable' in the Bible

Let the words of my mouth and the meditation of my heartBe acceptable in Your sight,O Lord, my rock and my Redeemer.

May He remember all your meal offeringsAnd find your burnt offering acceptable! Selah.

But as for me, my prayer is to You, O Lord, at an acceptable time;O God, in the greatness of Your lovingkindness,Answer me with Your saving truth.
