Shared ground
Psalm 2:12 closes the psalm with a final warning and a final refuge. The text presents two paths: showing allegiance to “the son” (“kiss the son”) or refusing and facing ruin. The warning is urgent because the son’s anger can “ignite quickly,” and the result is described as “perish in the way” (perishing while continuing on that course).
The ending shifts from warning rulers to a broad promise: “Blessed are all those who take refuge in him.” The refuge line is intentionally wide (“all”), and it frames safety and well-being as found by seeking protection under the authority of the one addressed.
Where interpretation differs (only where needed)
Who “the son” is. Some read “the son” primarily as the psalm’s royal figure in its original setting (an Israelite king spoken of with royal “son” language). Others read the psalm’s “son” as reaching beyond any single historical king to God’s ultimate anointed ruler, with later Scripture identifying that figure more specifically (compare Acts 13:33).
Who “him” is in “take refuge in him.” Some think “him” points back to the son, so refuge is sought in the king God has installed. Others think “him” points to the LORD more directly, so the final line underlines refuge in God, even if honoring the son is still required.
Why the disagreement exists
The psalm uses close, rapid references (“son … he … his … him”) without restating the subject each time, which leaves a real question about the final pronoun. Also, “son” language can function as normal royal language in Israel’s monarchy, yet Psalm 2 also speaks in global, ultimate terms (nations, ends of the earth), which invites readings that look beyond an ordinary reign.
What this passage clearly contributes
Explicitly, the verse teaches that God’s appointed ruler must be publicly honored, and that refusing that honor is not neutral—it carries consequences tied to the ruler’s anger and judgment. It also teaches that there is a true place of safety (“refuge”) offered to anyone who turns for protection to the one in authority. The passage does not explain the mechanics of that refuge; it simply asserts the blessed outcome for all who seek it, alongside the danger of persisting “in the way” of resistance.
