¹⁷And I forwarded them to the rulers with the money of the place, and I put words in their mouth to speak to their brethren the Nathinim with the money of the place, that they should bring us singers for the house of our God.

¹⁸And they came to us, as the good hand of our God was upon us, even a man of understanding of the sons of Mahli, the son of Levi, the son of Israel, and at the commencement came his sons and his brethren, eighteen.
