Romanos 11:33

O the depth

(Ο βαθος). Exclamation with omega and the nominative case of βαθος (see on 2 Corintios 8:2; Romanos 8:39). Paul's argument concerning God's elective grace and goodness has carried him to the heights and now he pauses on the edge of the precipice as he contemplates God's wisdom and knowledge, fully conscious of his inability to sound the bottom with the plummet of human reason and words.Unsearchable

(ανεξεραυνητα). Double compound (α privative and εξ) verbal adjective of ερευναω (old spelling -ευ-), late and rare word (LXX, Dio Cassius, Heraclitus), only here in N.T. Some of God's wisdom can be known (Romanos 1:20), but not all.Past tracing out

(ανεξιχνιαστο). Another verbal adjective from α privative and εξιχνιαζω, to trace out by tracks (ιχνος Romanos 4:12). Late word in Job (Job 5:9; Job 9:10; Job 34:24) from which use Paul obtained it here and Efesios 3:8 (only N.T. examples). Also in ecclesiastical writers. Some of God's tracks he has left plain to us, but others are beyond us.
