'Bow' in the Bible

Behold, I will cause those of the synagogue of Satan, who say that they are Jews and are not, but lie—I will make them come and bow down at your feet, and make them know that I have loved you.

I looked, and behold, a white horse, and he who sat on it had a bow; and a crown was given to him, and he went out conquering and to conquer.
