The Effect of Things
There are consequences of all behavior since all behavior is either sin or righteousness.
Introduction
v.18
Note that this pair has links to vv. 16–17. The wealth of the cruel man corresponds to deceptive wages as the honor given a kind woman is genuine. Also the health/self-inflicted pain of v. 17 corresponds to the life and death of v. 19.
v.19
The general idea of the verse is plain: righteousness insures a long and happy life, wickedness a premature or otherwise unhappy death
This pair has the chiastic pattern “wicked man / he who sows righteousness / righteousness/he who pursues evil.” The wages of sin are deceptive in that they are fleeting and illusory, whereas the wages of righteousness are permanent.
v.20
v.21
11:20–21 God’s attitude toward individuals (disgust/pleasure) in v. 20 corresponds to the outcome of their lives (inescapable trouble/deliverance) in v. 21. The language in v. 21 is also somewhat forensic in that the evil are convicted (“not go unpunished”) but the righteous acquitted (“go free”). God’s judgment follows his evaluation of people. On the other hand, the NIV may well be wrong to emend the text of v. 21b, as it has. The MT reads, “But the offspring of [the] righteous are delivered.” The implication is that one’s behavior effects not just oneself but one’s children as well.
