Psalm 2/Notes/Phrasal.v. 7.439504

The preposition אֶל modifying the verb of speaking ספּר indicates the topic of the discourse: "tell of the decree" (ESV, NJPS) or "tell about the decree" (cf. Gen 20:2—"And Abraham said of (אֶל) Sarah his wife, 'She is my sister'" [ESV]; cf. Isa 29:22; Ezek 21:33; Job 42:8. Similarly, with verbs of speaking, the preposition עַל can indicate "the focus of attention" (i.e., "about," "concerning").
