Jealousy & hatred
Joseph has no friends in his own house. He is going out to check on them per dads instruction.
Gen 37:18 Now when they saw him afar off, even before he came near them, they conspired against him to kill him.
19 Then they said to one another, “Look, this dreamer is coming!
20 “Come therefore, let us now kill him and cast him into some pit; and we shall say, ‘Some wild beast has devoured him.’ We shall see what will become of his dreams!”
They see him first. They hate him. Some want to kill him & then throw him in a pit. Then want to lie to dad. Hows those dreams going to happen now? This is in direct rebellion to God, for those were divine dreams. No Spirit lead person will act in opposition to the Fathers will. We may not understand them, but our spirit rejoices at the work God is doing, even in others. Sin only grows to more sin. It will always cost you more than you want to pay, keep you longer than you want to stay, takes you further than you want to go. Sin is a horrible slave master.
