Genesis 4:10

4:10 But the Lord said, “What have you done? The voice of your brother’s blood is crying out to me from the ground!

Psalms 50:21

50:21 When you did these things, I was silent,

so you thought I was exactly like you.

But now I will condemn you

and state my case against you!

Romans 3:20

3:20 For no one is declared righteous before him by the works of the law, for through the law comes the knowledge of sin.

sn What have you done? Again the Lord’s question is rhetorical (see Gen 3:13), condemning Cain for his sin.

tn The word “voice” is a personification; the evidence of Abel’s shed blood condemns Cain, just as a human eyewitness would testify in court. For helpful insights, see G. von Rad, Biblical Interpretations in Preaching; and L. Morris, “The Biblical Use of the Term ‘Blood,’” JTS 6 (1955/56): 77-82.

tn Heb “these things you did and I was silent.” Some interpret the second clause (“and I was silent”) as a rhetorical question expecting a negative answer, “[When you do these things], should I keep silent?” (cf. NEB). See GKC 335 §112.cc.

tn The Hebrew infinitive construct (הֱיוֹת, heyot) appears to function like the infinitive absolute here, adding emphasis to the following finite verbal form (אֶהְיֶה, ’ehyeh). See GKC 339-40 §113.a. Some prefer to emend הֱיוֹת (heyot) to the infinitive absolute form הָיוֹ (hayo).

tn Or “rebuke” (see v. 8).

tn Heb “and I will set in order [my case against you] to your eyes.” The cohortative form expresses the Lord’s resolve to accuse and judge the wicked.

sn An allusion to Ps 143:2.

tn Grk “because by the works of the law no flesh is justified before him.” Some recent scholars have understood the phrase ἒργα νόμου (erga nomou, “works of the law”) to refer not to obedience to the Mosaic law generally, but specifically to portions of the law that pertain to things like circumcision and dietary laws which set the Jewish people apart from the other nations (e.g., J. D. G. Dunn, Romans [WBC], 1:155). Other interpreters, like C. E. B. Cranfield (“‘The Works of the Law’ in the Epistle to the Romans,” JSNT 43 [1991]: 89-101) reject this narrow interpretation for a number of reasons, among which the most important are: (1) The second half of v. 20, “for through the law comes the knowledge of sin,” is hard to explain if the phrase “works of the law” is understood in a restricted sense; (2) the plural phrase “works of the law” would have to be understood in a different sense from the singular phrase “the work of the law” in 2:15; (3) similar phrases involving the law in Romans (2:13, 14; 2:25, 26, 27; 7:25; 8:4; and 13:8) which are naturally related to the phrase “works of the law” cannot be taken to refer to circumcision (in fact, in 2:25 circumcision is explicitly contrasted with keeping the law). Those interpreters who reject the “narrow” interpretation of “works of the law” understand the phrase to refer to obedience to the Mosaic law in general.

tn Grk “is.”
