שִׁמְעוּ־זֹ֭את כָּל־הָֽעַמִּ֑ים הַ֝אֲזִ֗ינוּ כָּל־יֹ֥שְׁבֵי חָֽלֶד׃
Hört dies, all ihr Völker, horcht auf, all ihr Weltbewohner!
Rashi on Psalms
Hear this, all you peoples Because this psalm is based on people who rely on their riches, he says, “all you peoples,” for they all require admonition.
Ibn Ezra on Psalms
"Listen" - to the message he gives, that addresses all in whose nostrils G-d (lit. hashem, the name) blew the breath of life. Therefore, "listen all who dwell on Earth".
Metzudat David on Psalms
"All ye people" - because everybody needs this lesson.
