'Regularly' in the Bible

So he left Asaph and his brothers there before the ark of the covenant of Yahweh to minister before the ark regularly {as each day required},

to offer burnt offerings regularly to Yahweh on the altar of burnt offering, morning and evening, according to all that was written in the law of Yahweh that he commanded concerning Israel.

and for every burnt offering offered to Yahweh, on Sabbaths, on new moon festivals, and at the appointed feasts, according to the customary number {required of them}, regularly before Yahweh.
