'Therein' in the Bible

that by them I may prove Israel, whether they will keep the way of Yahweh to walk therein, as their fathers did keep it, or not."

Abimelech fought against the city all that day; and he took the city, and killed the people who were therein: and he beat down the city, and sowed it with salt.

Samson said, "Let me die with the Philistines!" He bowed himself with all his might; and the house fell on the lords, and on all the people who were therein. So the dead that he killed at his death were more than those who he killed in his life.

Then the five men departed, and came to Laish, and saw the people who were therein, how they lived in security, in the way of the Sidonians, quiet and secure; for there was none in the land, possessing authority, that might put [them] to shame in anything, and they were far from the Sidonians, and had no dealings with any man.

There was no deliverer, because it was far from Sidon, and they had no dealings with any man; and it was in the valley that lies by Beth Rehob. They built the city, and lived therein.
