JMNT(i)
33 O, the depth of God's riches (wealth; resources) and wisdom and intimate, experiential knowledge and insight! How unsearchable (inscrutable) the effects of His decisions (the results of the distinctive separations, judicial awards, judgments and evaluations from Him), and untrackable (untraceable) His ways (paths; roads).
34 For, "Who knows (knew by intimate experience) the Lord's [= Yahweh's] mind? Or, who becomes (or: came to be) His planning adviser (His design counselor; the one who makes determinations with Him)?" [Isa. 40:13]
