Passage
Some trust in chariots, and some in horses: but we will call upon the name of the Lord, our God.
Some trust in chariots, and some in horses: but we will call upon the name of the Lord, our God.
Psalms 19:6 We will rejoice in thy salvation; and in the name of our God we shall be exalted.
Psalms 19:7 The Lord fulfil all thy petitions: now have I known that the Lord hath saved his anointed. He will hear him from his holy heaven: the salvation of his right hand is in powers.
Psalms 19:8 Some trust in chariots, and some in horses: but we will call upon the name of the Lord, our God.
Psalms 19:9 They are bound, and have fallen: but we are risen, and are set upright.
Psalms 19:10 O Lord, save the king: and hear us in the day that we shall call upon thee.
The verse centers on "some", "trust", "chariots", "horses", "call", "upon", and "name". It is saying that the verse draws attention to "some" and "trust", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "The Lord fulfil all thy petitions now..." into verse 9's "They are bound and have fallen but...", so "some" and "trust" 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 "some" and "trust" with trust shaped by these words, not by a vague optimism outside the passage.
