The New John Gill Exposition of the Entire Bible2 Kings 16:1
In the seventeenth year of Pekah the son of Remaliah Ahaz
the son of Jotham king of Judah began to reign.
] Jotham began to
reign in the second of Pekah, and he reigned sixteen years, and
therefore his last year would fall in the eighteenth of Pekah; but as
his first year might be at the beginning of the second of Pekah,
his last was towards the end of the seventeenth of Pekah's, as here;
see (2 Kings 15:32) .
