Why was David leaving home?

David's parents both passed away, and David was leaving his home in Essendean because he felt it was time to strike out on his own.

David Balfour was leaving home and going to Essendean because his Parents were died and he thinks that he have a good oppurtunity to make his fortune best and look for work.

The exact wordings of the novel are as follows:-

"I was seventeen years old and until then, had lived all my life in the village of Essendean, in the lowlands of Scotland. On that day, I locked the door of my childhood home for the last time. My father, a school master in the village, had been dead for three weeks, and it was time for me to leave home and look for work."

I hope you understand :)

And please answer to my question which is "what is the character sketch of Ebenezer? Explain in few words."

Thankyou!
