Passage
Wait on the LORD: be of good courage, and he shall strengthen thine heart: wait, I say, on the LORD.
Wait on the LORD: be of good courage, and he shall strengthen thine heart: wait, I say, on the LORD.
Psalms 27:12 Deliver me not over unto the will of mine enemies: for false witnesses are risen up against me, and such as breathe out cruelty.
Psalms 27:13 I had fainted, unless I had believed to see the goodness of the LORD in the land of the living.
Psalms 27:14 Wait on the LORD: be of good courage, and he shall strengthen thine heart: wait, I say, on the LORD.
The verse centers on "wait", "lord", "good", "courage", "shall", "strengthen", "thine", and "heart". It is saying that the verse draws attention to "wait" and "lord", so its meaning should be read from those terms before moving to application.
The prior verse says "I had fainted unless I had believed...", giving immediate footing for "wait" and "lord". 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 "wait" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
