Theophylact of Ohrid, on Rom 10:20

“But Isaias is bold, and saith: I was found by them that did not seek me: I appeared openly to them that asked not after me.”

“Having said that Moses speaks first, he mentions also another prophet, who says the same thing more clearly and openly. Isaiah, he says, "is very bold," that is, he strove to express the truth in all its nakedness and preferred to expose himself to danger rather than remain silent. "I was found," it says in him, "by those who did not seek Me" and who did not ask for Me (Isa. 65:1). Those whom Moses called a foolish nation, Isaiah named as those who neither sought nor asked, that is, ignorant people and enemies of knowledge. So from all this the Jews should have understood that some were rejected and others were accepted.”
