"there is no truth": Words of Torah are not being spoken, viz.: (Proverbs 22:23) "Buy truth and do not sell it."
"and there is no lovingkindness": There is no lovingkindness in the land, viz. (Psalms 33:5) "The lovingkindness of the L-rd fills the land."
"and there is no knowledge": Words of knowledge are not being spoken, viz. (Hoshea 4:6) "My people is silent, without knowledge; for you have silenced knowledge."
And it is written (Isaiah 5:24) "As straw will consume a tongue of fire, and hay will weaken a flame, etc." Now can straw consume fire? — "straw" here is Esav. So long as Israel "weaken" their hand from mitzvoth, Esav prevails over them.
