Joshua 24:19-20

If (as some read those words) we read this passage according to the original in the plural number: He is the holy Gods, meaning He, Jehovah existing in a threefold character of persons, the Holy Gods; this is a sweet and precious passage in confirmation of the Holy Trinity. Hear, O Israel, the Lord thy God is one Lord. A thing unnecessary to have been remarked, if at the same time it had not been suggested, that in this one eternal essence of the Godhead, there existed a plurality of persons. And hence, in the opening of the Bible, the phrase is the same plural: so in Solomon: Remember thy Creators; for so it is in the original. Ecclesiastes 12:1. Joshua's representing the difficulties, was not intended to put them off from their pious resolution; but only to forewarn them of the difficulty. Our dear Lord told his disciples somewhat similar, when he represented his service as taking up a cross, plucking out an eye, and cutting off an arm.
