Isaiah 59:15

Yea, truth faileth Lit. And truth is missing, conspicuous by its absence.

maketh himself a prey i.e. must submit to extortion (Psalms 76:6). Another, and possibly a better rendering is, "withdraws himself"; compare the peculiar use of the simple verb in Ruth 2:16 ("draw out" corn from the sheaf).

15b introduces the peroration of the discourse, in which the prophet describes the manner in which salvation shall at last "overtake" the sinful and misgoverned community. The logical development of the argument seems to be arrested by the conviction that the existing situation is hopeless, and only to be terminated through the personal intervention of Jehovah. This conviction clothes itself first of all in a prophetic vision of Jehovah as He appears to judgement; which is followed by an announcement of the consequences of His interposition for the two classes within Israel and for mankind at large. Although the transition in the middle of this verse is abrupt and unexpected there is no sufficient reason to doubt the unity of the discourse.
