A.T. Robertson Commentary Romans 10:20

"And Isaiah is very bold, and saith, I was found of them that sought me not; I became manifest unto them that asked not of me." — Romans 10:20 (ASV)

Is very bold (αποτολμα). Present active indicative of αποτολμαω, old word, to assume boldness (απο, off) and only here in N.T. Isaiah "breaks out boldly" (Gifford). Paul cites Isa 65:1 in support of his own courage against the prejudice of the Jews. See 9:30-33 for illustration of this point.

I was found (ευρεθην). First aorist passive indicative of ευρισκω.
