Mattityahu 5:33-35

Orthodox Jewish Bible

³³ Again, you have heard that it was said to the ancients, You shall not break your nederim (vows), but you shall repay your vows to Hashem.[T.N.See VAYIKRA 19:12; BAMIDBAR 30:3; DEVARIM 23:22]

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]).
