It it a general term that has a number of specialized meanings.  - The second "shall sit" is a very different word than the one above. It means "to let fall" or "to drop," but it has a lot of casual uses such putting things in motion and employing them. It, like the "sit" above begins with the prefix meaning "down." This word is in the future tense and in a form that indicates the subject, the apostles, acting on themselves.
