Genesis 37:14-18

Then he said to him, “Go now and see about the welfare of your brothers and the welfare of the flock, and bring word back to me.” So he sent him from the Valley of Hebron, and he came to Shechem.

A man found him, and behold, he was wandering in the field; and the man asked him, “What are you looking for?”

He said, “I am looking for my brothers; please tell me where they are pasturing the flock.”

Then the man said, “They have moved from here; for I heard them say, ‘Let’s go to Dothan.’ ” So Joseph went after his brothers and found them at Dothan. The Plot against Joseph

When they saw him from a distance, and before he came closer to them, they plotted against him to put him to death.
