John Gill Commentary Ezekiel 31:5

"Therefore its stature was exalted above all the trees of the field; and its boughs were multiplied, and its branches became long by reason of many waters, when it shot [them] forth." — Ezekiel 31:5 (ASV)

Therefore his height was exalted above all the trees of the field

His majesty, grandeur, and glory, were advanced above all princes, nobles, and people; all ranks and degrees of men, let them be compared to trees taller or lower.

and his boughs were multiplied, and his branches became long ; the provinces of his empire became more numerous, and were spread far and near, and reached to distant countries.

because of the multitude of waters, when he shot forth ; either the vast number of people, which were daily increasing, and were sent out to people distant colonies, newly subdued or planted; or because of the great traffic which was carried on in different parts, and the advantages arising from it.

The Targum is, ``therefore he was lifted up in his strength above all the kings of the earth, and his army was multiplied, and his auxiliaries prevailed over many people, through his victories''
