Thou shalt make two cherubims - What these were we cannot distinctly say. It is generally supposed that a cherub was a creature with four heads and one body: and the animals, of which these emblematical forms consisted, were the noblest of their kinds; the lion among the wild beasts, the bull among the tame ones, the eagle among the birds, and man at the head of all; so that they might be, says Dr. Priestley, the representatives of all nature. Concerning their forms and design there is much difference of opinion among divines. It is probable that the term often means a figure of any kind, such as was ordinarily sculptured on stone, engraved on metal, carved on wood, or embroidered on cloth. See on Exodus 35:8 (note). It may be only necessary to add, that cherub is the singular number; cherubim, not cherubims, the plural. See what has been said on this subject in the note on Genesis 3:24 (note).

He demands my very best as a condition of His enriching Presence. My prayers must be of "pure gold" if He is to meet me there. There must be nothing vulgar …

The Word
The third way to escape the wrath and curse of God, and obtain the benefit of redemption by Christ, is the diligent use of ordinances, in particular, the word, sacraments, and prayer.' I begin with the best of these ordinances. The word . . . which effectually worketh in you that believe.' 1 Thess 2:13. What is meant by the word's working effectually?
