Keil & Delitzsch

The rendering "regard me," so far as פּנה אל means God's observant and sympathising turning to any one (lxx ἐπιβλέπειν), corresponds to Psa 86:16; Lev 26:9. For this he longs, for men treat him as a stranger and refuse to have anything to do with him. יחיד is the only one of his kind, one who has no companion, therefore the isolated one. The recurrence of the same sounds עני אני is designedly not avoided. To whom could he, the isolated one, pour forth his affliction, to whom could he unveil his inmost thoughts and feelings? to God alone! To Him he can bring all his complaints, to Him he can also again and again always make supplication.
