'Yoke bars' in the Bible

Thus says the Lord to me, “Make for yourself bonds and yokes and put them on your neck,

Hananiah spoke in the presence of all the people, saying, “Thus says the Lord, ‘Even so within two full years I will break the yoke of Nebuchadnezzar king of Babylon from the neck of all the nations.’” Then the prophet Jeremiah went his way.

“Go and tell Hananiah, ‘The Lord says this, “You have broken yokes of wood, but you have made in their place bars of iron.”

“In Tehaphnehes the day will be darkWhen I break there the yoke bars of Egypt.Then the pride of her power will cease in her;A cloud will cover her,And her daughters will go into captivity.
