Passage
For they shall add to thee length of days, and years of life, and peace.
For they shall add to thee length of days, and years of life, and peace.
Proverbs 3:1 My son, forget not my law, and let thy heart keep my commandments.
Proverbs 3:2 For they shall add to thee length of days, and years of life, and peace.
Proverbs 3:3 Let not mercy aud truth leave thee, put them about thy neck, and write them in the tables of thy heart.
Proverbs 3:4 And thou shalt find grace, and good understanding before God and men.
The verse centers on "shall", "thee", "length", "days", "years", "life", and "peace". It is saying that the verse draws attention to "shall" and "thee", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "My son forget not my law and..." into verse 3's "Let not mercy aud truth leave thee...", so "shall" and "thee" belong inside that flow. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "shall" and "thee" with trust shaped by these words, not by a vague optimism outside the passage.
