John 8:20

These words spake he in the treasury, as he taught in the temple: and no man took him; because his hour had not yet come.

This area was actually called the court of women; but against the wall in that court were some large boxes to receive the offerings of the people; and thus this came to be called the treasury. The regular meeting place of the Sanhedrin was in earshot of this place, thus expediting their bringing the woman to Jesus (John 8:1-11). The significance of Jesus' teaching here without molestation derives from its being at the very center of Jewish activities.

His hour had not yet come ... God's providential care would continue to guard Jesus until the time appointed for his death.
