'Open' in the Bible

My eyes are wasted with weeping, the inmost parts of my body are deeply moved, my inner parts are drained out on the earth, for the destruction of the daughter of my people; because of the young children and babies at the breast who are falling without strength in the open squares of the town.

They say to their mothers, Where is grain and wine? when they are falling like the wounded in the open squares of the town, when their life is drained out on their mother's breast.

The mouths of all our haters are open wide against us.
