As soone as they heare, they shall obey me: the strangers shall be in subiection to me.
As soone as they heare, they shall obey me: the strangers shall be in subiection to me.
Psalms 18:42 Then I did beate them small as the dust before the winde: I did treade them flat as the clay in the streetes.

Psalms 18:44 As soone as they heare, they shall obey me: the strangers shall be in subiection to me.
Psalms 18:45 Strangers shall shrinke away, and feare in their priuie chambers.
Psalms 18:46 Let the Lord liue, and blessed be my strength, and the God of my saluation be exalted.
The verse centers on "soone", "heare", "shall", "obey", "strangers", and "subiection". It is saying that the verse draws attention to "soone" and "heare", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 43's "Thou hast deliuered me from the contentions..." into verse 45's "Strangers shall shrinke away and feare in...", so "soone" and "heare" 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 "soone" and "heare" with trust shaped by these words, not by a vague optimism outside the passage.
