As soon as they hear of me they shall obey me. The foreigners shall submit themselves to me.
Psalms 18:42 Then I beat them small as the dust before the wind. I cast them out as the mire of the streets.

Psalms 18:44 As soon as they hear of me they shall obey me. The foreigners shall submit themselves to me.
Psalms 18:45 The foreigners shall fade away, and shall come trembling out of their close places.
Psalms 18:46 Yahweh lives; and blessed be my rock. Exalted be the God of my salvation,
The verse centers on "soon", "hear", "shall", "obey", "foreigners", "submit", and "themselves". It is saying that the verse draws attention to "soon" and "hear", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 43's "You have delivered me from the strivings..." into verse 45's "The foreigners shall fade away and shall...", so "soon" and "hear" 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 "soon" and "hear" with trust shaped by these words, not by a vague optimism outside the passage.
