Genesis 40:23 - The Sin of Forgetting

Yet did not the chief butler remember Joseph, but forgat him.

This was a case of "out of sight, out of mind" in the face of good times. The butler had good intentions on helping Joseph but he forgot him as though he were dead (Psalm 31:12). When times are good we have a bad habit of forgetting those that helped us succeed (Amos 6:6, Hosea 13:6). This sin of forgetfulness happens when we become overly preoccupied with our own affairs which overshadows the interest of others.

Genesis 32:26 - How to get your breakthrough.

And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.

Although Jacob was weak and tied from wrestling all night, he was not going to give up until he got his blessing. As he desperately held on with all his might, crying and begging for his favor (Hosea 12:4), he got his breakthrough.
