Solemn, binding statements made in God's name. The OT forbids the making of oaths in the name of other gods and the NT suggests that it is best to refrain from making oaths.
Oaths are considered binding
Numbers 30:2 See also Deuteronomy 23:21; Matthew 23:16–22
If a man makes a vow to the LORD or swears an oath to obligate himself by a pledge, he must not break his word; he must do everything he has promised.
Oaths to be taken only in God's name
Deuteronomy 6:13 See also Psalm 24:3–4; Jeremiah 12:16
Fear the LORD your God, serve Him only, and take your oaths in His name.
False oaths forbidden
Leviticus 19:12 See also Exodus 20:7 parallel Deuteronomy 5:11; Leviticus 6:3–5; Zechariah 5:3–4
You must not swear falsely by My name and so profane the name of your God. I am the LORD.

But Abram replied to the king of Sodom, “I have raised my hand to the LORD God Most High, Creator of heaven and earth, that I will not accept even a thread, or a strap of a sandal, or anything that belongs to you, lest you should say, ‘I have made Abram rich.’
Unwise or thoughtless oaths
Genesis 25:33 See also Leviticus 5:4; Matthew 14:6–7 parallel Mark 6:22–23
