Who had understanding in the visions of God - Another reading, supported by the Septuagint, and some ancient versions, is: "who instructed him in the fear of God."

In the days of Zechariah - Who this was we know not, but by the character that is given of him here. He was wise in the visions of God - in giving the true interpretation of Divine prophecies. He was probably the tutor of Uzziah.

And he sought God in the days of Zechariah,.... Not that Zechariah, the last of the prophets save one, he lived three hundred years after this; nor he that Joash slew; but, as it may seem, a son of his, perhaps the same with him in Isaiah 8:2,

who had understanding in the visions of God: who either had prophetic visions granted to him, or had divine wisdom to interpret such that others had; or, as others think, had a gift of interpreting the prophecies of others, the writings of Moses and David, &c. to which the Targum seems to agree; which paraphrases it,"who taught in the fear of the Lord;''with which agree the Septuagint, Syriac, and Arabic versions; some copies read "in the fear of God"; as an ancient manuscript mentioned by Junius, and so the Talmud (l):

and, as long as he sought the Lord, God made him to prosper; in his kingdom, and against his enemies; even so long as he abode by the word, worship, and ordinances of God, of which instances are given, as follow.

(l) Vid. Buxtorf. Lex. in rad.

And he sought God in the days of {c} Zechariah, who had understanding in the visions of God: and as long as {d} he sought the LORD, God made him to prosper.

(c) This was not the Zechariah that was the son of Jehoiada, but some other prophet of that name.

(d) For God never forsakes any who seek him, and therefore man is the cause of his own destruction.

in the visions...: Heb. in the seeing of God

5. he sought God in the days of Zechariah-a wise and pious counsellor, who was skilled in understanding the meaning and lessons of the ancient prophecies, and who wielded a salutary influence over Uzziah.

26:1-15 As long as Uzziah sought the Lord, and minded religion, God made him to prosper. Those only prosper whom God makes to prosper; for prosperity is his gift. Many have owned, that as long as they sought the Lord, and kept close to their duty, they prospered; but when they forsook God, every thing went cross. God never continues either to bless the indolent or to withhold his blessing from the diligent. He will never suffer any to seek his face in vain. Uzziah's name was famed throughout all the neighbouring countries. A name with God and good people makes truly honourable. He did not delight in war, nor addict himself to sports, but delighted in husbandry.
