Passage
For sake me not, O Lord my God: do not thou depart from me.
For sake me not, O Lord my God: do not thou depart from me.
Psalms 37:20 But my enemies live, and are stronger than I: and they that hate me wrongfully are multiplied.
Psalms 37:21 They that render evil for good, have detracted me, because I followed goodness.
Psalms 37:22 For sake me not, O Lord my God: do not thou depart from me.
Psalms 37:23 Attend unto my help, O Lord, the God of my salvation.
The verse centers on "sake", "lord", "thou", and "depart". It is saying that the verse draws attention to "sake" and "lord", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "They that render evil for good have..." into verse 23's "Attend unto my help O Lord the...", so "sake" and "lord" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "sake" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
