'Resentful' in the Bible

and they have no real root in themselves, so they endure only for a little while; then, when trouble or persecution comes because of the word, immediately they [are offended and displeased at being associated with Me and] stumble and fall away.

Blessed [joyful, spiritually favored] is he who does not take offense at Me.”

It is not rude; it is not self-seeking, it is not provoked [nor overly sensitive and easily angered]; it does not take into account a wrong endured.

Husbands, love your wives [with an affectionate, sympathetic, selfless love that always seeks the best for them] and do not be embittered or resentful toward them [because of the responsibilities of marriage].
