Do err in their heart; they do not only sin through infirmity, and the violence and surprisal of temptations, but their hearts are insincere and inconstant, and given to backsliding, and therefore there is no hopes of their amendment. Compare Psalms 78:8. They have not known; or, they do not know, to wit, with a practical and useful knowledge, as that word commonly notes in Scripture. They did not rightly understand, nor duly consider, nor seriously lay to heart; they remain ignorant after all my teachings and discoveries of myself to them. My ways; either,
1. My laws or statutes, which are frequently called God's ways. Or rather,
2. My works, as it is expressed, Psalms 95:9, which also are commonly so called. They did not know nor consider and remember those great things which I had wrought for them and among them.
