The reader will observe that chapter v. 1-13 forms a part of chapter iv. Both are comprehended under one head, and present the doctrine of the sin-offering in all its applications, from the bullock to the handful of flour. Each class of offering is introduced by the words, "And the Lord spake unto Moses." Thus, for example, the sweet savor offerings (chap. i.-iii.) are introduced by the words, "The Lord called unto Moses." These words are not repeated until chapter iv. 1, where they introduce the sin-offering. They occur again at chapter v. 14, where they introduce the trespass-offering for wrongs done "in the holy things of the Lord;" and again at chapter vi. 1, where they introduce the trespass-offering for wrongs done to one's neighbor. This classification is beautifully simple, and will help the reader to understand the different classes of offering. As to the different grades in each class, whether "a bullock," "a ram," "a female," "a bird," or "a handful of flour," they would seem to be so many varied applications of the same grand truth. The effect of individual sin could not extend beyond individual conscience. The sin of "a ruler," or of "one of the common people," could not, in its influence, reach "the altar of incense"--the place of priestly worship; neither could it reach to "the vail of the sanctuary"--the sacred boundary of God's dwelling-place in the midst of His people. It is well to ponder this. We must never raise a question of personal sin or failure in the place of priestly worship or in the assembly; it must be settled in the place of personal approach. Many err as to this. They come into the assembly, or into the ostensible place of priestly worship, with their conscience defiled, and thus drag down the whole assembly and mar its worship. This should be closely looked into, and carefully guarded against. We need to walk more watchfully, in order that our conscience may ever be in the light. And when we fail, (as, alas! we do in many things,) let us have to do with God in secret about our failure, in order that true worship and the true position of the assembly may always be kept with fullness and clearness before the soul.
