Taught of God (didaktoi qeou). A free quotation from Isaiah 54:13 with this phrase in the LXX. There is here the ablative case qeou with the passive verbal adjective didaktoi (Robertson, Grammar, p. 516). In 1 Thessalonians 4:9 we have the compound verbal qeodidaktoi. The same use of didakto with the ablative occurs in 1 Corinthians 2:13 . And hath learned (kai maqwn). Second aorist active participle of manqanw. It is not enough to hear God's voice. He must heed it and learn it and do it. This is a voluntary response. This one inevitably comes to Christ.
