Passage
Let them not depart from thy eyes, keep them in the midst of thy heart:
Let them not depart from thy eyes, keep them in the midst of thy heart:
Proverbs 4:19 The way of the wicked is darksome: they know not where they fall.
Proverbs 4:20 My son, hearken to my words, and incline thy ear to my sayings.
Proverbs 4:21 Let them not depart from thy eyes, keep them in the midst of thy heart:
Proverbs 4:22 For they are life to those that find them, and health to all flesh.
Proverbs 4:23 With all watchfulness keep thy heart, because life issueth out from it.
The verse centers on "depart", "eyes", "keep", "midst", and "heart". It is saying that the verse draws attention to "depart" and "eyes", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "My son hearken to my words and..." into verse 22's "For they are life to those that...", so "depart" and "eyes" 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 "depart" and "eyes" with trust shaped by these words, not by a vague optimism outside the passage.
