[21:30] 1 tn The form לְנֶגֶד (lÿneged) means “against; over against; in opposition to.” The line indicates they cannot in reality be in opposition, for human wisdom is nothing in comparison to the wisdom of God (J. H. Greenstone, Proverbs, 232).
[21:30] 2 sn The verse uses a single sentence to state that all wisdom, understanding, and advice must be in conformity to the will of God to be successful. It states it negatively – these things cannot be in defiance of God (e.g., Job 5:12-13; Isa 40:13-14).
