A statement that an affiant “firmly believes” the contents of the affidavit imports a strong or high degree of belief, and is equivalent to saying that he “verily” believes it. Bradley v. Eccles, 1 Browne (Pa.) 258; Thompson v. White, 4 Serg. & R.(Pa.) 137. The operative words in a bond or recognizance, that the obligor is held and”firmly bound,” are equivalent to acknowledgment of indebtedness and promise to pay. Sliattuck v. People, 5 I1L 477.
