'Thirty ninth' in the Bible

Shallum the son of Jabesh began to reign in the thirty-ninth year of Uzziah king of Judah, and he reigned {a full month} in Samaria.

In the thirty-ninth year of Azariah king of Judah, Menahem the son of Gadi began to reign over Israel [for] ten years in Samaria.

And in the thirty-ninth year of his reign, he fell {severely} ill in his feet. But even in his illness he did not seek Yahweh, but [only] among the healers.
