Comentario sobre Salmos 7:15

Behold, he travails Heb. יחבל an expression of conception and birth, as (in Song 8:5): “there your mother was in travail with you (חבלתך).”

Behold, he travaileth with iniquity; Yea, he hath conceived mischief, and brought forth falsehood. – He compares the thoughts of the heart with conception, and says their issuing in speech or conduct is like the pangs of a woman at childbirth. If so, the comparison is between speech and birth-pains, and (between) conduct and childbearing. And he says that he speaks evil, because he has conceived it in his heart and brought it forth in his mouth for execution. And iniquity and mischief and. falsehood have all one meaning, though the words are different.

he conceives mischief, and gives birth to lies Whatever he begets and toils, everything betrays him. The adage says: Whatever lies beget, diminution takes.
