Ezequiel 3:20

When a righteous man doth turn from his righteousness. — Quite independently of any theological question, it is undeniable that the Scripture here, as often elsewhere, represents the upright man as exposed to temptation, and in danger of falling into sin. The duty of the prophet, therefore, is not only to seek to turn the wicked from his evil way, but also to warn the righteous against falling into the same path. Both terms must necessarily be taken as comparative; but they show that there was even now a considerable difference in character among the captives.

I lay a stumblingblock before him. — A “stumbling-block” is anything at which people actually stumble, whether intended for that purpose or, on the contrary, designed for their highest good. Thus Christ is foretold as a stumbling-block to both the houses of Israel (Isaías 8:14), and is several times spoken of as such by the apostles (1 Coríntios 1:23; Romanos 9:32; 1 Pedro 2:8). The word is used oftener by Ezekiel than by all the other Old Testament writers together; in Ezequiel 7:19 the riches of the people are spoken of as their stumbling-block, and in Ezequiel 44:12 (marg.) the sinful Levites are described as a stumbling-block. The meaning here is plainly, “when a man perverts any of God’s gifts or providences into an occasion of sin.”
