Amsal 30:6

30:6 Do not add to his words,

lest he reprove you, and prove you to be a liar. ¹ 

Amsal 3:12

3:12 For the Lord disciplines ²  those he loves,

just as a father ³  disciplines ⁴  the son in whom he delights.

[30:6]  ¹ tn The form of the verb is a Niphal perfect tense with a vav consecutive from the root כָּזַב (kazav, “to lie”). In this stem it has the ideas of “been made deceptive,” or “shown to be false” or “proved to be a liar.” One who adds to or changes the word of the Lord will be seen as a liar.

[3:12]  ² tn Heb “chastens.” The verb יָכַח (yakhakh) here means “to chasten; to punish” (HALOT 410 s.v. יכח 1) or “to correct; to rebuke” (BDB 407 s.v. 6). The context suggests some kind of corporeal discipline rather than mere verbal rebuke or cognitive correction. This verse is quoted in Heb 12:5-6 to show that suffering in the service of the Lord is a sign of membership in the covenant community (i.e., sonship).

[3:12]  ³ tc MT reads וּכְאָב (ukh’av, “and like a father”) but the LXX reflects the Hiphil verb וְיַכְאִב (vÿyakh’iv, “and scourges every son he receives”). Both readings fit the parallelism; however, it is unnecessary to emend MT which makes perfectly good sense. The fact that the writer of Hebrews quotes this passage from the LXX and it became part of the inspired NT text does not mean that the LXX reflects the original Hebrew reading here.

[3:12]  ⁴ tn The verb “disciplines” does not appear in the Hebrew text, but is implied by the parallelism; it is supplied in the translation for the sake of clarity.
