Deuteronomy 29:29
29. The secret things belong unto the Lord—This verse has no apparent connection with the thread of discourse. It is thought to have been said in answer to the looks of astonishment or the words of inquiry as to whether they would be ever so wicked as to deserve such punishments. The recorded history of God's providential dealings towards Israel presents a wonderful combination of "goodness and severity." There is much of it involved in mystery too profound for our limited capacities to fathom; but, from the comprehensive wisdom displayed in those parts which have been made known to us, we are prepared to enter into the full spirit of the apostle's exclamation, "How unsearchable are his judgments" (Ro 11:33).
Isaiah 55:8-9
8. For—referring to Isa 55:7. You need not doubt His willingness "abundantly to pardon" (compare Isa 55:12); for, though "the wicked" man's "ways," and "the unrighteous man's thoughts," are so aggravated as to seem unpardonable, God's "thoughts" and "ways" in pardoning are not regulated by the proportion of the former, as man's would be towards his fellow man who offended him; compare the "for" (Ps 25:11; Ro 5:19).
9. (Ps 57:10; 89:2; 103:11). "For" is repeated from Isa 55:8. But MAURER, after the negation, translates, "but."
