The theme proposed of the first part of his discourse.
Vanity of vanities - Hebraism for the most utter vanity. So “holy of holies” (Exo 26:33); “servant of servants” (Gen 9:25). The repetition increases the force.
all - Hebrew, “the all”; all without exception, namely, earthly things.
vanity - not in themselves, for God maketh nothing in vain (1Ti 4:4, 1Ti 4:5), but vain when put in the place of God and made the end, instead of the means (Psa 39:5, Psa 39:6; Psa 62:9; Mat 6:33); vain, also, because of the “vanity” to which they are “subjected” by the fall (Rom 8:20).
