actually to blow away or down (to express which נשׁב or נשׁף would be used), but either to “snub,” or, what is more appropriate to Psa 10:5, to blow upon them disdainfully, to puff at them, like הפּיח in Mal 1:13, and flare rosas (to despise the roses) in Prudentius. The meaning is not that he drives his enemies away without much difficulty, but that by his proud and haughty bearing he gives them to understand how little they interfere with him.
Verses 6-7
Then in his boundless carnal security he gives free course to his wicked tongue. That which the believer can say by reason of his fellowship with God, בּל־אמּוט (Psa 30:7; Psa 16:8), is said by him in godless self-confidence. He looks upon himself in age after age, i.e., in the endless future, as אשׁר לא ברע, i.e., as one who (אשׁר as in Isa 8:20) will never be in evil case (ברע as in Exo 5:19; 2Sa 16:8). It might perhaps also be interpreted according to Zec 8:20, Zec 8:23 (vid., Köhler, in loc.): in all time to come (it will come to pass) that I am not in misfortune. But then the personal pronoun (אני or הוּא) ought not be omitted; whereas with our interpretation it is supplied from אמּוט, and there is no need to supply anything if the clause is taken as an apposition: in all time to come he who.... In connection with such unbounded self-confidence his mouth is full of אלה, cursing, execratio (not perjury, perjurium, a meaning the word never has), מרמות, deceit and craft of every kind, and תּך, oppression, violence. And that which he has under his tongue, and consequently always in readiness for being put forth (Psa 140:4, cf. Psa 66:17), is trouble for others, and in itself matured wickedness. Paul has made use of this Psa 10:7 in his contemplative description of the corruptness of mankind, Rom 3:14.
Verse 8
The ungodly is described as a lier in wait; and one is reminded by it of such a state of anarchy, as that described in Hos 6:9 for instance. The picture fixes upon one simple feature in which the meanness of the ungodly culminates; and it is possible that it is intended to be taken as emblematical rather than literally. חצר (from חצר to surround, cf. Arab. hdr , hṣr, and especially hdr) is a farm premises walled in (Arab. hadar , hadâr , hadâra), then losing the special characteristic of being walled round it
