John Gill's Bible Commentary Ver. 5. Also he strengthened himself , etc.] In the Lord his God, and fortified his city, and put it in the best manner of defence he could: and built up all the wall that was broken ; which was broken from the gate of Ephraim to the corner gate by Joash king of Israel; and though it might have been repaired by Uzziah, it might again be broken down in the times of Ahaz, by Pekah, king of Israel, or some other enemy, (see Chronicles 25:3 26:9 28:6,7) and raised it up to the towers ; from the corner tower to the tower of the gate of Ephraim, which, as before observed, had been broken down: and another wall without ; a second wall, either all around the city, or at such a part of it which was weakest; Josephus says the city of Jerusalem had three walls about it: and repaired Millo in the city of David ; a wall on the north side of the city: and made darts and shields in abundance ; darts to cast from the walls of the city, to annoy the enemy with, and shields to defend them from those of the enemy.
Matthew Henry Commentary
Verses 1-23 - Those who trust God with their safety, must use proper means, else the tempt him. God will provide, but so must we also. Hezekiah gathered his people together, and spake comfortably to them. A believing confidenc in God, will raise us above the prevailing fear of man. Let the goo subjects and soldiers of Jesus Christ, rest upon his word, and boldl say, Since God is for us, who can be against us? By the favour of God enemies are lost, and friends gained.
