What does Psalm 18:44 mean?
David writes that foreigners chose to be in subjection to him as soon as they heard about his successful victories. This is a continuation of praise to God, for enabling David's success (Psalm 18:31–43).Second Samuel 8:9–10 is an example of a foreign nation responding humbly to David upon hearing of his military success (2 Samuel 8:1–8). When Toi, king of Hamath, heard about David vanquishing Hadadezer's whole army. Toi dispatched his son on a diplomatic mission to David. Joram presented David with articles of silver, gold and bronze. That same chapter indicates that after David struck down 18,000 Edomites, he put garrisons throughout Edom, "and all the Edomites became David's servants" (2 Samuel 8:13–14).
When Jesus the Messiah rules the planet (Revelation 20:4–6), nations will bow before him and worship him. Zechariah14:16 promises, "Then everyone who survives of all the nations that have come up against Jerusalem shall go up year after year to worship the King, the Lord of hosts."
