'Opportune' in the Bible

Ask your young men and they will tell you. Therefore let my young men find favor in your sight [and be well-treated], for we have come on a good (festive) day. Please, give whatever you find at hand to your servants and to your son David.’”

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].

There they will cry out,“Pharaoh king of Egypt was all noise;he let the opportune moment pass.”
