He hath said in his heart, I shall not be moved: for I shall never be in adversity.
I shall not be moved - from my present prosperity.
For (I shall) never (be) in adversity - literally, 'as being from generation to generation х lªdor (H1755) waador (H1755)] one who (am) not (and never have been) in adversity.' The wicked man is regarded as an ideal person, who lives on from generation to generation in the same course of successful villany.
