אַ֥שְֽׁרֵי הַגֶּ֗בֶר אֲשֶׁר־שָׂ֣ם יְ֭הֹוָה מִבְטַח֑וֹ וְֽלֹא־פָנָ֥ה אֶל־רְ֝הָבִ֗ים וְשָׂטֵ֥י כָזָֽב׃
Happy is the man that hath made the LORD his trust, and hath not turned unto the arrogant, nor unto such as fall away treacherously.
Shenei Luchot HaBerit
ולא זכר שר המשקים את יוסף וישכחהו . The lesson here is clearly that one must only place one's trust in G–d Himself.
