Kept the charge of the Lord - When we consider the strong disposition which this people ever testified to follow their own will in all things, we may be well surprised to find them, in these journeyings, so implicitly following the directions of God. There could be no trick or imposture here. Moses, had he been the most cunning of men, never could have imitated the appearances referred to in this chapter. The cloud, and every thing in its motion, was so evidently supernatural, that the people had no doubt of its being the symbol of the Divine presence. God chose to keep this people so dependent upon himself, and so submissive to the decisions of his own will, that he would not even give them regular times of marching or resting; they were to do both when and where God saw best. Thus they were ever kept ready for their march, though perfectly ignorant of the time when they should commence it. But this was all well; they had the presence of God with them; the cloud by day and the fire by night demonstrated that God was amongst them. Reader, thou art here a tenant at will to God Almighty. How soon, in what place, or in what circumstances, he may call thee to march into the eternal world, thou knowest not. But this uncertainty cannot perplex thee, if thou be properly subject to the will of God, ever willing to lose thy own in it. But thou canst not be thus subject, unless thou have the testimony of the presence and approbation of God. How awful to be obliged to walk into the valley of the shadow of death without this! Reader, prepare to meet thy God.

Numbers 10:2 "Make yourself two trumpets of silver, of hammered work you shall make them; and you shall use them for summoning the congregation and for having the camps set out.

The Publication of the Gospel
The Lord gave the word: great was the company of those that published it [or of the preachers] P erhaps no one Psalm has given greater exercise to the skill and patience of commentators and critics, than the sixty-eighth. I suppose the difficulties do not properly belong to the Psalm, but arise from our ignorance of various circumstances to which the Psalmist alludes; which probably were, at that time, generally known and understood. The first verse is the same with the stated form of benediction …
