The sons of Shemaiah: Othni, Rephael, Obed, and Elzabad, whose brothers [were] sons of ability, Elihu and Semakiah.

All these from the sons of Obed-Edom, they and their sons, and their brothers [were] men of ability with strength for service; sixty-two of Obed-Edom.

And Meshelemiah had sons and brothers, sons of ability, eighteen.

For the Hebronites: Hashabiah and his brothers, one thousand seven hundred men of ability, [were] over the administration of Israel beyond the Jordan westward, for all the work of Yahweh and for the service of the king.

And his brothers, sons of ability, [were] two thousand seven hundred heads of the {families}, and King David appointed them over the Reubenites, the Gadites, and the half-tribe of Manasseh, for every matter of God and matter of the king.

Then David assembled all the commanders of Israel, the commanders of the tribes and the commanders of working groups who served the king, and the commanders of thousands, the commanders of hundreds, and the commanders over all the property of the king and his sons, with the court officials and mighty warriors, and all the mighty warriors of ability, at Jerusalem.
