'Heedless' in the Bible

'No domestic is able to serve two lords, for either the one he will hate, and the other he will love; or one he will hold to, and of the other he will be heedless; ye are not able to serve God and mammon.'

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].
