The apostle Paul (an expositor we may depend upon) has given us the true sense of these verses, and told us what was the event they pointed at and were fulfilled in, namely, the calling in of the Gentiles and the rejection of the Jews, by the preaching of the gospel, Rom 10:20, Rom 10:21.
Commenting on Isaiah 65:1-7
A people that provoketh me to anger continually to my face,.... They committed their sins openly, without any fear of the divine Being, and in defiance of him, not at all awed by his omniscience and omnipresence; they committed them in the open streets, and even in the temple, the place of the divine residence; and these they did constantly, which provoked him to anger...
continually--answering to "all the day" (Isa 65:2). God was continually inviting them, and they continually offending Him (Deu 32:21). to my face--They made no attempt to hide their sin (Isa 3:9). Compare "before Me" (Exo 20:3). in gardens--(See on Isa 1:29; Isa 66:17; Lev 17:5). altars of brick--Hebrew, "bricks." God had commanded His altars to be of unhewn stone (Exo 20:25).
