Psalms 78:2 - Wesley's Explanatory Notes

Parable — Weighty sentences. Dark sayings — Not that the words are hard to be understood, but the things, God's transcendent goodness, their unparallel'd ingratitude; and their stupid ignorance and insensibleness, under such excellent teachings of God's word and works, are prodigious and hard to be believed. Of old — Of things done in ancient times.
