It is scarcely worth observing that the letters called heemantic by the Hebrew grammarians, and which are used in forming the derivatives from the roots, are taken from the first word in this verse, האמנתי heemanti, "I have believed;" as the prefixes in that language are found in the technical words משה וכלב Mosheh vecaleb, "Moses and Caleb;" and the formatives of the future are found in the word איתן eythan, "strength."
