“cities.” This is the figure of speech metonymy for the people who live in the cities. The metonymy emphasizes that Jeremiah will speak to people from many different parts of the country.

“to worship.” Or, “to bow down to.” The same Hebrew verb, shachah (#07812 שָׁחָה), is translated as both “bow down” and “worship;” traditionally “worship” if God is involved and “bow down” if people are involved, but the verb and action are the same, the act of bowing down is the worship. The common biblical way of bowing down before people or God was to fall to one’s knees and bow the upper body to the earth. [For more on bowing down, see commentary on 1 Chron. 29:20].
