'City gate' in the Bible

After Ahab had left, the hand of the LORD came upon Elijah, and he tucked his mantle into his belt and outran Ahab in a race to the city gate of Jezreel.

Now the king of Israel and King Jehoshaphat of Judah were each sitting on their respective thrones, arrayed in their robes, on the threshing floor at the entrance to the city gate of Samaria, and all of the prophets were prophesying in front of them.
