'Sixteenth' in the Bible

for Bilgah the fifteenth, for Immer the sixteenth,

at the sixteenth to Hananiah, his sons and his brethren, twelve;

And they begin on the first of the first month to sanctify, and on the eighth day of the month they have come to the porch of Jehovah, and they sanctify the house of Jehovah in eight days, and on the sixteenth day of the first month they have finished.
