Mattityahu 5:34-35

Orthodox Jewish Bible

³⁴ But I say to you, Do not swear shevuot (oaths) at all, neither by Shomayim, for it is the kes malchut of Hashem (throne of G-d),

³⁵ nor by haaretz, for it is the hadom (footstool) of his feet, nor by Yerushalayim, for it is the kiryat melech rav (city of the great king, TEHILLIM 48:3[2]).
