'Oath' in the Bible
whereupon with an oath he professed to give her whatever she might ask.
and again did he deny with an oath -- 'I have not known the man.'
a prophet, therefore, being, and knowing that with an oath God did swear to him, out of the fruit of his loins, according to the flesh, to raise up the Christ, to sit upon his throne,
and they were more than forty who made this conspiracy by oath,
for men indeed do swear by the greater, and an end of all controversy to them for confirmation is the oath,
in which God, more abundantly willing to shew to the heirs of the promise the immutability of his counsel, did interpose by an oath,
And inasmuch as it is not apart from oath, (for those indeed apart from oath are become priests,
and he with an oath through Him who is saying unto him, 'The Lord sware, and will not repent, Thou art a priest -- to the age, according to the order of Melchisedek;')
for the law doth appoint men chief priests, having infirmity, but the word of the oath that is after the law appointeth the Son -- to the age having been perfected.
And before all things, my brethren, do not swear, neither by the heaven, neither by the earth, neither by any other oath, and let your Yes be Yes, and the No, No; that under judgment ye may not fall.
