'Cords' in the Bible

Woe unto them that draw iniquity with cords of vanity, and sin as it were with a cart rope:

For this cause the cords of my heart are sounding for Moab, and I am full of sorrow for Kir-heres.

Look upon Zion, the city of our solemnities: thine eyes shall see Jerusalem a quiet habitation, a tabernacle that shall not be taken down; not one of the stakes thereof shall ever be removed, neither shall any of the cords thereof be broken.

Your cords have become loose; they were not able to make strong the support of their sails, the sail was not stretched out: then the blind will take much property, the feeble-footed will make division of the goods of war.

Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes;

Isn't this the fast that I have been choosing: to loose the bonds of injustice, and to untie the cords of the yoke, and to let the oppressed go free, and to break every yoke?
