'Forgets' in the Bible

Who leaves the companion (husband) of her youth,And forgets the covenant of her God.

for once he has looked at himself and gone away, he immediately forgets what he looked like.

But he who looks carefully into the perfect law, the law of liberty, and faithfully abides by it, not having become a [careless] listener who forgets but an active doer [who obeys], he will be blessed and favored by God in what he does [in his life of obedience].
