Ezekiel 3:20

Again, when a righteous man doth turn from his righteousness ,.... This is to be understood not of one that is truly righteous, or is justified by the righteousness of Christ; for such can never turn from that righteousness, or be in an unjustified state; seeing that is the righteousness of God, and an everlasting one; but of one that is denominated righteous, from "his" own righteousness, from a righteousness "which he hath done", as is afterwards expressed; one that is outwardly righteous before men, that is outwardly reformed, that has a righteousness of his own, consisting of a little negative holiness, and a few moral performances; from such righteousness a man may apostatize, and go into a vicious course of life:

and commit iniquity ; live in sin, make a trade of it; lead a life, the whole series and course of which is nothing else but sin; in this sense, one that is born of God, and has the righteousness of Christ revealed from faith to faith unto him, and lives by faith upon it, cannot commit sin, 1 John 3:9 ;

and I lay a stumbling block before him ; the Targum renders it, "the stumbling block of sins"; which designs either an occasion of sinning, which God permits, leaving him to his own lusts, and suffering him to fall thereby; and by this means he is discovered to be what he is, not a truly righteous man, but only one in appearance; that looked like a righteous person, but secretly a sinner, and now the Lord by such means exposes him openly; so Jarchi and other Jewish Rabbins; but Kimchi's father interprets the stumbling block of prosperity in this world F21 Vid. T. Bab. Yoma, fol. 86. 2. : or rather the punishment of sin is meant, as Kimchi himself observes; and the Septuagint renders it "torment"; since this follows up on his turning from righteousness, and committing sin; and seems to be explained by the next clause:

he shall die ; the second death:

because thou hast not given him warning : of the dreadful evil of apostasy, and the sad estate of apostates, and the danger they are in, their last estate being worse than the first:

he shall die in his sin ; of apostasy, and for it, being never to be recovered and brought to repentance:

and his righteousness which he hath done shall not be remembered ; according to the "Keri" or marginal reading it is, "his righteousnesses"; all his works of righteousness which he hath done; and which reading is followed by the Targum, Septuagint, Vulgate Latin, and the eastern versions; these shall not be remembered, neither in this world nor in that to come; no account shall be taken of them, nor shall they be reckoned as a righteousness unto him:

but his blood will I require at thine hand ; See Gill on Ezekiel 3:18 .
