'Opportune Time' 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].

But an opportune time [finally] came [for Herodias]. Herod on his birthday gave a banquet for his officials (nobles, courtiers) and military commanders and the leading men of Galilee.
