Then said Judah to Onan, Go in unto thy brothers wife, and fulfil the duty of a brother-in-law unto her, - and raise up seed, to thy brother.

So he left there, before the ark of the covenant of Yahweh, Asaph and his brethren, - to be in attendance before the ark continually, for the duty of a day on its day;

For, their duty, was - to be in attendance upon the sons of Aaron, in the laborious work of the house of Yahweh, over the courts, and over the chambers, and over the purifying of everything holy, - and doing the laborious work, of the house of God;

even according to the duty of each a day upon its own day, offering up according to the commandment of Moses, for the sabbaths, and for the new moons, and for the appointed feasts, three times in the year, - in the festival of unleavened cakes and in the festival of weeks, and in the festival of booths;

and he caused to stand, according to the regulation of David his father, the courses of the priests over their service and of the Levites over their charges, to offer praise and to minister before the priests, for the duty of each day upon its own day, and the gate-keepers in their courses, at every several gate, - for, such, was the commandment of David the man of God;

neither departed they from the commandment of the king, concerning the priests and the Levites as to any duty, or as to the treasuries.

Train up a youth, in the direction of his duty, even when he becometh old, he will not depart from it.

Hear, thou, my son, and be wise, and lead forward, in duty, thy heart.
