'Sixteenth' in the Bible

the fifteenth to Bilgah, the sixteenth to Immer,

for the sixteenth to Hananiah, his sons and his brothers, twelve:

Now they began on the first [day] of the first month to sanctify, and on the eighth day of the month came they to the porch of Yahweh; and they sanctified the house of Yahweh in eight days: and on the sixteenth day of the first month they made an end.
