Passage
A psalm for David himself. Mercy and judgment I will sing to thee, O Lord: I will sing,
A psalm for David himself. Mercy and judgment I will sing to thee, O Lord: I will sing,
Psalms 100:1 A psalm for David himself. Mercy and judgment I will sing to thee, O Lord: I will sing,
Psalms 100:2 And I will understand in the unspotted way, when thou shalt come to me. I walked in the innocence of my heart, in the midst of my house.
Psalms 100:3 I will not set before my eyes any unjust thing: I hated the workers of iniquities.
The verse centers on "mercy", "psalm", "david", "himself", "judgment", "sing", "thee", and "lord". It is saying that the verse draws attention to "mercy" and "psalm", so its meaning should be read from those terms before moving to application.
The next verse adds "And I will understand in the unspotted...", so "mercy" and "psalm" should be read forward into that movement. 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 "mercy" and "psalm" with trust shaped by these words, not by a vague optimism outside the passage.
