Its urge is toward you, but you can rule over it. Cain gives no answer to God. Instead he speaks to Abel, to his brother. In most such passages of Torah, what follows these words is a quotation, a saying. But here there are no words, there is no quotation.
Some contemporary translations leave an empty space, three dots, a silence.
No more can Cain speak to Abel than to God. So the story continues, wordless. So it was through their being in the fields that Cain rose up against his brother Abel and killed him. Again with our own children vividly before our eyes, we can see the story in a new way. Surely we can share Cain's initial anger at his Parent's favoritism.
