לֹ֥א תִשָּׂ֛א אֶת־שֵֽׁם־יְהוָ֥ה אֱלֹהֶ֖יךָ לַשָּׁ֑וְא כִּ֣י לֹ֤א יְנַקֶּה֙ יְהוָ֔ה אֵ֛ת אֲשֶׁר־יִשָּׂ֥א אֶת־שְׁמ֖וֹ לַשָּֽׁוְא׃ (ס)
Huwag mong bibigkasin nang walang kabuluhan ang pangalan ng Walang-Hanggan na iyong Diyos, sapagkat hindi ituturing ng Walang-Hanggan na walang sala ang sinumang bumibigkas ng Kanyang pangalan nang walang kabuluhan.
Mishneh Torah, Sabbath
Four concepts were said regarding Sabbath, two from the Torah, and two from the words of the Sages and explicated through the Prophets. From the Torah: "Remember" (Exodus 20:8) and "Observe" (Deuteronomy 5:12). And explicated through the Prophets: Honor and delight, as it is said, "And call the sabbath a delight, And the holy of the LORD honourable" (Isaiah 58:13).
Mishneh Torah, Negative Mitzvot
Not to violate an oath (even when it only accompanies the statement of what one intends to do), as it is said, “Ye shall not swear by My name falsely” (Lev. 19:12).
Mishneh Torah, Negative Mitzvot
Not to swear needlessly, as it is said, “Thou shalt not take the name of the Lord, thy God, in vain” (Ex. 20:7).
