'Freely' in the Bible

O generation, you see the word of Yahweh. Have I been a desert to Israel? Or a land of great darkness? Why do my people say, 'We roam about freely, we will not come again to you'?

And Jeremiah said unto Zedekiah, Thus saith Jehovah the God of hosts, the God of Israel: If thou wilt freely go forth to the king of Babylon's princes, then thy soul shall live, and this city shall not be burned with fire; and thou shalt live, and thy house.
