المزامير ١٦:٤

As he loves the saints so, on the other hand, he abhors the apostates and their idols. אהר מהרוּ is to be construed as an appositional relative clause to the preceding: multi sunt cruciatus (cf. Psa 32:10) eorum, eorum scil. qui alium permutant. The expression would flow on more smoothly if it were ירבּוּ: they multiply, or increase their pains, who..., so that אחר מהרו would be the subject, for instance like אהבו ה (he whom Jahve loves), Isa 48:14. This Psa 16:4 forms a perfect antithesis to Psa 16:3. In David's eyes the saints are already the glorified, in whom his delight centres; while, as he knows, a future full of anguish is in store for the idolatrous, and their worship, yea, their very names are an abomination to him. The suffixes of נסכּיהם and שׁמותם might be referred to the idols according to Exo 23:13; Hos 2:19, if אהר be taken collectively as equivalent to אחר ם, as in Job 8:19. But it is more natural to assign the same reference to them as to the suffix of עצּבותם, which does not signify "their idols" (for idols are עצבּים), but their torments, pains (from עצּבת derived from עצּב), Psa 147:3; Job 9:28. The thought is similar to Ti1 6:10, ἑαυτοὺς περιέπειραν ὀδύναις ποικίλαις. אהר is a general designation of the broadest kind for everything that is not God, but which man makes his idol beside God and in opposition to God (cf. Isa 42:8; Isa 48:11). מהרוּ cannot mean festinant, for in this signification it is only found in Piel מהר, and that once with a local, but not a personal, accusative of the direction, Nah 2:6. It is therefore to be rendered (and the perf. is also better adapted to this meaning): they have taken in exchange that which is not God (מהר like המיר, Psa 106:20; Jer 2:11). Perhaps (cf. the phrase זנה אהרי) the secondary meaning of wooin…

This psalm has something of David in it, but much more of Christ. It begins with such expressions of devotion as may be applied to Christ; but concludes with such confidence of a resurrection (and so timely a one as to prevent corruption) as must be applied to Christ, to him only, and cannot be understood of David, as both St. Peter and St. Paul have observed, Act 2:24; Act 13:36. For David died, and was buried, and saw corruption. I. David speaks of himself as a member of Christ, and so he speaks the language of all good Christians, professing his confidence in God (Psa 16:1), his consent to him (Psa 16:2), his affection to the people of God (Psa 16:3), his adherence to the true worship of God (Psa 16:4), and his entire complacency and satisfaction in God and the interest he had in him (Psa 16:5-7). II. He speaks of himself as a type of Christ, and so he speaks the language of Christ himself, to whom all the rest of the psalm is expressly and at large applied (Act 2:25, etc.). David speaks concerning him (not concerning himself), "I foresaw the Lord always before my face," etc. And this he spoke, being a prophet (v. 30, 31). He spoke, 1. Of the special presence of God with the Redeemer in his services and sufferings (Psa 16:8). 2. Of the prospect which the Redeemer had of his own resurrection and the glory that should follow, which carried him cheerfully through his undertaking (Psa 16:9-11). Michtam of David.

16:4 The psalmist dissociates himself from ungodly worship, rituals, and words (see 15:3-5).
