פֶּ֥ן אֶשְׂבַּ֨ע ׀ וְכִחַשְׁתִּי֮ וְאָמַ֗רְתִּי מִ֥י יְה֫וָ֥ה וּפֶֽן־אִוָּרֵ֥שׁ וְגָנַ֑בְתִּי וְ֝תָפַ֗שְׂתִּי שֵׁ֣ם אֱלֹהָֽי׃ (פ)
Lest I be full, and deny, and say: ‘Who is the LORD?’ Or lest I be poor, and steal, And profane the name of my God.
Rashi on Proverbs
and deny the existence of the Holy One, blessed be He, out of my extreme haughtiness. Now what is the denial? And I say, “Who is the Lord?” Meaning, there is no God.
Rashi on Proverbs
and take hold of the name of my God to become accustomed to swearing by it falsely.
