Obededom was the Levite who was suddenly put in charge of the Ark of God because David had messed up (which included one of his men being struck down by God because of David's misguided faith) and was now terrified of God (check out 1 Chronicles 13).
The Ark stayed with Obededom and his family for three months.
Scripture says, "God had indeed blessed him."
The result of this blessing was 62 people serving God with strength.
When some duty, something is thrust upon us, and we know that we know that we know we have to do it, we need to do it well.
It is from God.
He will reward us for our faithful service.
