The substance of the oath of the grand jury is, that they shall diligently inquire into and true presentments make of all such matters and things as shall be given them in charge, or shall otherwise come to their knowledge touching their present service; that they shall present no person through malice, hatred or ill-will; nor shall they leave any unpresented through fear, favor or affection, or for any fee or reward, or for any hope or promise thereof; but in all presentments they shall present the truth, the whole truth, and nothing but the truth, according to the best of their skill and understanding.11

The oath is administered to the foreman alone; after which the other jurors are sworn to well and truly keep and observe, on their parts, the oath taken by their foreman.
