The Torah portion of Naso deals with the laws concerning oaths and vows. The underlying principle of truthfulness in oaths connects to the broader Noahide prohibition against blasphemy.
The prohibition of swearing falsely is discussed in this portion, (Numbers 5:5–10), describing the laws of a person who swears falsely or acts deceitfully. The Noahide prohibition against blasphemy is connected to respecting the name of G-d (Maimonides Kings 9:1) and personal truthfulness.

This is rooted in the teachings of the Seven Laws of Noah, which are universal commandments given by G-d for all humanity. Both swearing falsely and breaking one’s word undermine social trust and justice, which are core aspects of the Noahide laws. The Torah emphasizes the seriousness of making false oaths. Upholding one’s commitments and promises is a fundamental aspect of integrity. For Noahides, as well as Jews, this principle aligns with the Torah values of honesty and justice.

A Noahide is committed to not swearing falsely and to keeping their word. This commitment is directly connected to the universal ethical principles derived from the Seven Laws of Noah and the teachings found in the Torah portion of Naso. Both emphasize the importance of honesty, and justice, reinforcing the moral framework that guides Noahides and aligning with the broader values of the Torah.

As we are in a special era and approaching the redemption by Moshiach, it is seen how important it is to apply the moral guidance of the 7 Noahide laws which can enhance moral conduct and the coming of the Messianic era.
