Adam Clarke on Acts 7:9

And the patriarchs - The twelve sons of Jacob, thus called because each was chief or head of his respective family or tribe.

Moved with envy - Ζηλωσαντες. We translate ζηλος variously: zeal or fervent affection, whether its object be good or bad, is its general meaning; and ζηλοω signifies to be indignant, envious, etc. See the note on Act 5:17. The brethren of Joseph, hearing of his dreams, and understanding them to portend his future advancement, filled with envy, (with which no ordinary portion of malice was associated), sold Joseph into the land of Egypt, hoping by this means to prevent his future grandeur; but God, from whom the portents came, was with him, and made their envy the direct means of accomplishing the great design.
