Isaiah
Isaiah 3:3ESV·traditional attribution

the captain of fifty and the man of rank, the counselor and the skillful magician and the expert in charms.

Matthew Henry Presbyterian @wholebiblehenry

The prophet, in the close of the foregoing chapter, had given a necessary caution to all not to put confidence in man, or any creature; he had also given a general reason for that caution, taken from the frailty of human life and the vanity and weakness of human powers.

Commenting on Isaiah 3:1-8

John Gill Reformed Baptist @doctorgill

The captain of fifty,.... A semi-centurion, such an one as in Kg2 1:9. So far should there be from being captains of thousands, and of hundreds, that there should not be one of fifty: and the honourable man; by birth, breeding, and behaviour, through riches and greatness; and one of power and authority among the people, and in their favour and esteem: and the counsellor...

Jamieson-Fausset-Brown Reformed @jfbcommentary

captain of fifty--not only captains of thousands, and centurions of a hundred, but even semi-centurions of fifty, shall fail. honourable--literally, "of dignified aspect." cunning--skilful. The mechanic's business will come to a standstill in the siege and subsequent desolation of the state; artisans are no mean "stay" among a nation's safeguards. eloquent orator--rather, as Vulgate, "skilled in whispering," that is, incantation (Psa 58:5).
