JMNT(i)
5 And further, you have entirely forgotten (or: been oblivious of) the calling-near (the relief, aid, comfort and encouragement) which keeps on speaking-through (discoursing; reasoning through and conversing; laying out the issue in every direction) to you as to sons: "My son, do not be neglecting (giving little care to) the Lord's discipline (education; child-training), neither be exhausted (dissolved; = fall apart) while being continually scrutinized or convicted (exposed and put to the test; or: reproved) by (or: under) Him,
6 for whom the Lord [= Yahweh] is loving, He is continuously and progressively educating (or: disciplining; child-training), and He is periodically scourging every son whom He is taking alongside with His hands (accepting; receiving)." [Prov. 3:11-12]
7 [So] be constantly enduring (or: You folks are continuing to remain supportively under) with a view to education, discipline and child-training: as to sons is God Himself continuously bringing [it] to you. For who is a son (or: what son is there) whom a father is not disciplining, educating and training?
8 But if you are without education, discipline and training, of which all have become partakers (common participants; partners), accordingly you are really illegitimates (= rabbinic term mamzer: child of a prohibited marriage [Lev. 18], or of uncertain fatherhood) and not sons.
