The Lord killeth - God is the arbiter of life and death; he only can give life, and he only has a right to take it away.
He bringeth down to the grave - The Hebrew word שאול sheol, which we translate grave, seems to have the same meaning in the Old Testament with ἁδης, hades in the New, which is the word generally used by the Septuagint for the other. It means the grave, the state of the dead, and the invisible place, or place of separate spirits. Sometimes we translate it hell, which now means the state of perdition, or place of eternal torments; but as this comes from the Saxon, to cover or conceal, it means only the covered place. In some parts of England the word helling is used for the covers of a book, the slating of a house, etc. The Targum seems to understand it of death and the resurrection. "He kills and commands to give life; he causes to descend into Sheol, that in the time to come he may bring them into the lives of eternity," i.e., the life of shame and everlasting contempt, and the life of glory.
