19Again I ask: Did Israel not understand? First, Moses says,

“I will make you envious by those who are not a nation;

I will make you angry by a nation that has no understanding.”^j

20And Isaiah boldly says,

“I was found by those who did not seek me;

I revealed myself to those who did not ask for me.”^k

21But concerning Israel he says,

“All day long I have held out my hands

to a disobedient and obstinate people.”^l
