1 Chronicles 25:26

The nineteenth to Mallothi, he, his sons, and his brethren, were twelve:

Mallothi stood as head of the nineteenth division in the arrangement of twenty-four musical courses established under David. His course numbered twelve men in all, counting Mallothi himself together with his sons and his brethren. This placing by courses belonged to a carefully ordered system appointing distinct companies to their service in the house of the Lord.
