'Bars' in the Bible

The tree of the field shall yield its fruit, and the earth shall yield its increase, and they shall be secure in their land; and they shall know that I am Yahweh, when I have broken the bars of their yoke, and have delivered them out of the hand of those who made slaves of them.

and you shall say, I will go up to the land of unwalled villages; I will go to those who are at rest, who dwell securely, all of them dwelling without walls, and having neither bars nor gates;
