If there be in the land famine - pestilence - The Fourth case includes several kinds of evils:

1. Famine; a scarcity or total want of bread, necessarily springing from the preceding cause, drought.

2. Pestilence; any general and contagious disease.

3. Blasting; any thing by which the crops are injured, so that the ear is never matured; but instead of wholesome grain, there is a black offensive dust.

4. Mildew; any thing that vitiates or corrodes the texture of the stalk, destroys the flowers and blossoms, or causes the young shaped fruits to fall off their stems.

5. Locust, a well known curse in the East, a species of grasshopper that multiplies by millions, and covers the face of the earth for many miles square, destroying every green thing; leaving neither herb nor grass upon the earth, nor leaf nor bark upon the trees.

6. Caterpillar; the locust in its young or nympha state. The former refers to locusts brought by winds from other countries and settling on the land; the latter, to the young locusts bred in the land.

7. An enemy, having attacked their defenced cities, the keys and barriers of the land.

8. Any other kind of plague; that which affects the surface of the body; blotch, blain, leprosy, ophthalmia, etc.

9. Sickness; whatever impaired the strength, or affected the intestines, disturbing or destroying their natural functions.

All such cases were to be brought before the Lord, the persons having a deep sense of the wickedness which induced God thus to afflict, or permit them to be afflicted: for only those who knew the plague of their own hearts, (1 Kings 8:38), the deep-rooted moral corruption of their nature, and the destructive nature and sinfulness of sin, were likely to pray in such a manner as to induce God to hear and forgive.

The next words are, WHICH ART IN HEAVEN. From this we are not to infer that he is enclosed and confined within the circumference of heaven, as by a kind of boundaries. Hence Solomon confesses, "The heaven of heavens cannot contain thee" (1 Kings 8:27); and he himself says by the Prophet, "The heaven is my throne, and the earth is my footstool" (Isa. 56:1); thereby intimating, that his presence, not confined to any region, is diffused over all space. But as our gross minds are unable to conceive of …

The Whole Heart
LET me give the principal passages in which the words "the whole heart," "all the heart," are used. A careful study of them will show how wholehearted love and service is what God has always asked, because He can, in the very nature of things, ask nothing less. The prayerful and believing acceptance of the words will waken the assurance that such wholehearted love and service is exactly the blessing the New Covenant was meant to make possible. That assurance will prepare us for turning to the Omnipotence …

The Gospel of John
As we turn to the fourth Gospel we come to entirely different ground from that which we have traversed in the other three. True, the period of time which is covered by it, is the same as in the others; true, that some of the incidents that have already been looked at will here come before us again; and true it is that he who has occupied the central position in the narratives of the first three Evangelists, is the same One that is made preeminent by John; but otherwise, everything here is entirely …
