What's prohibited in the Bible is swearing FALSE oaths, that is, calling on God to witness as truth what one knows to be false, or that one doesn't intend to perform.

but the previous poster (Steve Shaw) who mentioned Jesus in passing

Even Jesus thought that saying yes or no should be good enough for anybody.

was correct, assuming Uncle Dave's Bible contains Matthew's Gospel, where in chapter 5 verses 34-37 Jesus is quoted as saying, "But I say unto you, Swear not at all; neither by heaven; for it is God's throne: Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King. Neither shalt thou swear by thy head, because thou canst not make one hair white or black. But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil." (That's the somewhat archaic King James Version; the less archaic New International Version translates "         But I tell you, Do not swear at all: either by heaven, for it is God's throne; or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. And do not swear by your head, for you cannot make even one hair white or black. Simply let your 'Yes' be 'Yes,' and your 'No,' 'No'; anything beyond this comes from the evil one.")
