delusions - (2Th 2:11), answering to “their own ways” (Isa 66:3; so Pro 1:31). However, the Hebrew means rather “vexations,” “calamities,” which also the parallelism to “fears” requires; “choose their calamities” means, “choose the calamities which they thought to escape by their own ways.”
their fears - the things they feared, to avert which their idolatrous “abominations” (Isa 66:3) were practiced.
I called ... none ... answer - (See on Isa 65:12; see on Isa 65:24; see on Jer 7:13).
did ... chose - not only did the evil deed, but did it deliberately as a matter of choice (Rom 1:32). “They chose that in which I delighted not”; therefore, “I will choose” that in which they delight not, the “calamities” and “fears” which they were most anxious to avert.
