I was displeased

"I was angry" or "I was greatly unhappy"

They have always gone astray in their hearts

They have not known my ways

This speaks of a manner of conducting one's life as if it were a way or a path. Alternate translation: "They have not understood how I want them to conduct their lives" (See: rc://en/ta/man/translate/figs-metaphor)
