Therefore I will prayse thee, O Lord, among the nations, and wil sing vnto thy Name.
Therefore I will prayse thee, O Lord, among the nations, and wil sing vnto thy Name.
Psalms 18:47 It is God that giueth me power to auenge me, and subdueth the people vnder me.
Psalms 18:48 O my deliuerer from mine enemies, euen thou hast set mee vp from them, that rose against me: thou hast deliuered mee from the cruell man.
Psalms 18:49 Therefore I will prayse thee, O Lord, among the nations, and wil sing vnto thy Name.
Psalms 18:50 Great deliuerances giueth hee vnto his King, and sheweth mercie to his anoynted, euen to Dauid, and to his seede for euer.
The verse centers on "therefore", "prayse", "thee", "lord", "nations", "sing", "vnto", and "name". It is saying that the verse draws attention to "therefore" and "prayse", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 48's "O my deliuerer from mine enemies euen..." into verse 50's "Great deliuerances giueth hee vnto his King...", so "therefore" and "prayse" 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 "therefore" and "prayse" with trust shaped by these words, not by a vague optimism outside the passage.
