Genesis 39:9

39:9 There is no one greater in this household than I am. He has withheld nothing from me except you because you are his wife. So how could I do such a great evil and sin against God?”

Genesis 42:22

42:22 Reuben said to them, “Didn’t I say to you, ‘Don’t sin against the boy,’ but you wouldn’t listen? So now we must pay for shedding his blood!”

tn The nuance of potential imperfect fits this context.

tn Heb “and also his blood, look, it is required.” God requires compensation, as it were, from those who shed innocent blood (see Gen 9:6). In other words, God exacts punishment for the crime of murder.
