Genesis 31:36
And Jacob was wroth, and chode with Laban: and Jacob answered and said to Laban, What is my trespass? what is my sin, that thou hast so hotly pursued after me?
Cross-reference
Laban's accusation in 31:26 — why Jacob fled secretly and without farewell — is the direct catalyst for Jacob's heated response in 31:36.
In Genesis 30:2, Jacob's anger burns at Rachel's accusation over childlessness — the same Jacob now channeling that burning anger toward her father Laban.
Genesis 49:7 condemns Simeon and Levi's fierce anger after Shechem — Jacob who now burns with justified fury will later judge anger itself as dangerous.
In Numbers 16:15, Moses protests 'I have not taken one donkey from them' — the same innocent-man defense Jacob mounts here, denying wrongdoing to clear his name.
Jeremiah asks the king 'What wrong have I done?' — the same defensive posture as Jacob. Both men, falsely accused, demand to know the charge against them.
Jacob's anger is provoked by a false accusation — a justifiable cause for anger. This fits the principle of being angry without sinning.
Jacob's bold, confrontational speech exemplifies this proverb: the righteous stand firm, while the wicked flee. Jacob doesn't cower before Laban's accusations.
