'Law' in the Bible

Now Hobab the Kenite, Moses' father-in-law, had come up out of the town of palm-trees, with the children of Judah, into the waste land of Arad; and he went and was living among the Amalekites;

Now Heber the Kenite, separating himself from the rest of the Kenites, from the children of Hobab, the brother-in-law of Moses, had put up his tent as far away as the oak-tree in Zaanannim, by Kedesh.

Then the Philistines said, Who has done this? And they said, Samson, the son-in-law of the Timnite, because he took his wife and gave her to his friend. So the Philistines came up and had her and her father's house burned.

And his father-in-law, the girl's father, kept him there for three days; and they had food and drink and took their rest there.

Now on the fourth day they got up early in the morning and he made ready to go away; but the girl's father said to his son-in-law, Take a little food to keep up your strength, and then go on your way.

And the man got up to go away, but his father-in-law would not let him go, so he took his rest there again for the night.

And when they got up to go away, his father-in-law, the girl's father, said to him, Now evening is coming on, so do not go tonight; see, the day is almost gone; take your rest here and let your heart be glad, and tomorrow early, go on your way back to your house.
