The Lord our God spake unto us in Horeb. — The “Lord our God,” “Jehovah our Elohim,” is the watchword of the whole book.
Ye have dwelt long enough in this mount. — From the beginning of the second month of the first year of the exodus (Exodus 19:1) to the twentieth day of the second month of the second year (Numbers 10:11). This was the period of organisation, in which the people received the Law and were organised as a church militant, an army encamped around the tabernacle of God. This year and its institutions fill up exactly one-third of the text of the Pentateuch.
