in front of, or in the presence of, someone or something (especially a king or God)
This little word points to where one thing or person stands in relation to another: in front of it, or in its presence. In the night visions of Daniel it can be purely physical, marking one beast set apart from the beasts before it, or horns torn out from in front of another.
Far more often it places a person in the presence of someone greater. People are brought before the king, they speak and answer before him, and Daniel kneels and prays before his God. To stand before a king or before God is to be in their sight and under their authority, and this is the word's home ground in the court stories of Daniel and Ezra.
It also carries a polite habit of the Aramaic court. Rather than say the king decided something, the text says it seemed good before him; rather than say the king sent an order, it says the order went out from before him. The same care surrounds God: mercy is sought from before heaven, and Daniel says that before God he was found innocent, meaning in God's own judgment. The wording keeps a respectful distance, letting the king or God stand behind the action instead of being named as its plain subject.
