'Block' in the Bible

"When all of this happens, I'm going to set aside a grave site for Gog in Israel's Traveler's Valley, near the approach to the Dead Sea. She will block off everyone who tries to bypass it. There they will bury Gog, and rename the area "Valley of Gog's Gang'.

They passed the first guard, then the second, and came to the iron gate that led into the city. It opened by itself for them, and they went outside and proceeded one block when the angel suddenly left him.
