13 - The Lucky Number

The Ariza"l writes that the world is built of the 22 letters of the Hebrew alphabet. The nekudot (vowels) represent God's guidance of the world. There are a total of ten Hebrew vowels, but since tzeirei has two dots and segol has three that adds up to a total of thirteen. These represent the 13 attributes with which God runs the world. Each attribute contains within it the full gamut of spiritual power. Spiritual powers are called in Hebrew sefirot. As there are ten sefirot, the 13 attributes represent 130 distinct powers.

As such, when Adam sinned he damaged the way the world was running. He defiled in some manner those 130 powers with which God was running the world. That is why he spent 130 years repenting for his sin. It was not until the time of Jacob who had 130 years of difficult life that the process of redemption from the damage really began. It culminated in the birth of Moses to his mother who was then 130 years old. That is why she saw that he was good when he was born, because he represented the good that was now coming to be after all the bad since the sin of Adam.
