And he reigned over all the kings from the river even unto the land of the Philistines, and to the border of Egypt.

And the priests, and the Levites, that are in all Israel, have stationed themselves by him, out of all their border,

The Ammonites paid tribute to Uzziah, and his reputation extended as far as the border with Egypt as he became stronger and stronger.
