'Back' in the Bible

The man who stood among the myrtle trees answered, "They are the ones Yahweh has sent to go back and forth through the earth."

They reported to the angel of Yahweh who stood among the myrtle trees, and said, "We have walked back and forth through the earth, and behold, all the earth is at rest and in peace."

Indeed, who despises the day of small things? For these seven shall rejoice, and shall see the plumb line in the hand of Zerubbabel. These are the eyes of Yahweh, which run back and forth through the whole earth."

The strong went out, and sought to go that they might walk back and forth through the earth: and he said, "Go around and through the earth!" So they walked back and forth through the earth.

"I will strengthen the house of Judah, and I will save the house of Joseph, and I will bring them back; for I have mercy on them; and they will be as though I had not cast them off: for I am Yahweh their God, and I will hear them.
