Genesis 2:2

Gen. 2:2. "And on the seventh day God ended all his works." The [Hebrew] word translated work, which comes from [the Hebrew word for] angel or messenger, and therefore most properly signifies a work done in the execution of some function to which the workman is appointed, as the angel, messenger, officer, or workman of another; and so is fitly used concerning the work of creation; which was performed by the Son of God, who is often called the angel of the Lord: he being the Father's great officer, and artificer, through whom he performs all his work, and executes his eternal counsels and purposes.
