SEV Biblia, Chapter 5:35
ni por la tierra, porque es el estrado de sus pies; ni por Jerusaln, porque es la ciudad del gran Rey.
John Gill's Bible Commentary
Ver. 35. Nor by the earth, for it is his footstool , etc.] That the Jews were wont to swear by the earth, is clear from the above mentioned instances; and is condemned by Christ for this reason, because the earth is Gods footstool, referring, as before, to ( Isaiah 66:1) on which he treads; and where he also manifests forth his glory, and is a considerable part of the work of his hands. Neither by Jerusalem , which the Jews used to swear by: such forms of vows as these are to be met with in their writings f330 ; as the altar, as the temple, lwryk , as Jerusalem; that is, by Jerusalem, I vow I will do this, or the other thing. R. Judah says, he that says Jerusalem (i.e. as Bartenora observes f331 , without the note of comparison, as) says nothing. In the Gemara it is, he that says as Jerusalem, does not say anything, till he has made his vow concerning a thing, which is offered up in Jerusalem.
Dr. Lightfoot has produced forms of vowing and swearing, which have not occurred to me. Jerusalem; lwryl , for, or unto Jerusalem, which exactly answers to eiv Ierosoluma , here; and by Jerusalem; The reason given for prohibiting this kind of oath, is; for it is the city of the great king : not of David, but of the King of kings, the Lord of hosts; who had his residence, and his worship, here; (see Psalm 48:2).
Matthew Henry Commentary
Verses 33-37 - There is no reason to consider that solemn oaths in a court of justice or on other proper occasions, are wrong, provided they are taken with due reverence. But all oaths taken without necessity, or in commo conversation, must be sinful, as well as all those expressions whic are appeals to God, though persons think thereby to evade the guilt of swearing. The worse men are, the less they are bound by oaths; the better they are, the less there is need for them. Our Lord does no enjoin the precise terms wherein we are to affirm or deny, but such constant regard to truth as would render oaths unnecessary.
