What does Proverbs 3:27 mean?

Solomon now directs his student's attention to others. The phrasing used here highlights this as a duty: we are not to "withhold good." That implies this "good" is something we're obligated to give others. In more relaxed English, this is like saying, "treat others right." For that reason, this first instruction touches on the modern use of the word "honor," as used for meeting an obligation. Especially when something good is expected, or owed, we should actively seek to fulfill that command. This is re-emphasized in the following verse (Proverbs 3:28) This doing good, or honoring, can take many different forms.

A child can honor parents by being obedient and respectful (Ephesians 6:1–2). Parents can honor their children by not picking on them for every little thing. Instead, they ought to consider their children a stewardship from the Lord and rear them in the discipline and instruction of the Lord (Ephesians 6:4).

Servants or employees can honor an employer by working hard and sincerely as unto the Lord (Ephesians 6:5–7). Masters or employers should treat their employees fairly (Ephesians 6:9). An employer can honor loyal, productive employees by granting a promotion, a gift of appreciation, or a raise.

Young people can honor and respect senior citizens (1 Peter 5:5).

Church members can honor their spiritual leaders by paying them well for their faithful service (1 Timothy 5:17) and by "[esteeming] them very highly in love because of their work" (1 Thessalonians 5:12–13).
