Charles Ellicott Commentary Proverbs 30:18

"There are three things which are too wonderful for me, Yea, four which I know not:" — Proverbs 30:18 (ASV)

Too wonderful for me.— The wonder in Agur’s eyes seems to be that none of the four leave any trace behind them. (Compare to Wisdom 5:10 and following) For a spiritual interpretation of these and other passages in this chapter, see Bishop Wordsworth’s Commentary.
