And from the part given to the children of Israel, take one out of every fifty, from the persons, and from the oxen and asses and sheep, and give it to the Levites who have the care of the House of the Lord.

`And from the sons of Israel's half thou dost take one possession out of fifty, of man, of the herd, of the asses, and of the flock, of all the cattle, and thou hast given them to the Levites keeping the charge of the tabernacle of Jehovah.'

Out of the moiety also of the children of Israel thou shalt take the fiftieth head of persons, and of oxen, and asses, and sheep, and of all beasts, and thou shalt give them to the Levites that watch in the charge of the tabernacle of the Lord.

And of the children of Israel's half, thou shalt take one portion of fifty, of the persons, of the oxen, of the asses, and of the small cattle, of every [kind of] beasts, and thou shalt give them unto the Levites, who keep the charge of the tabernacle of Jehovah.
