Then the children kept the charge of the Lord. Some, [1] in my opinion, extend this too far, thinking that when the cloud tarried, the children of Israel, being as it were at leisure, employed themselves in the worship of God; but I restrict it rather to that heedfulness which is then praised at some length. To keep the charge (custodiam,) then, is equivalent to regarding the will of God with the greatest earnestness and care. For, when the cloud had begun to rest in any place, the people knew that they were to remain there; but if on the next day they were not attentive, the cloud might vanish, and thus their neglect and carelessness might deprive them of this incomparable advantage. To this end it is said immediately afterwards that, If for one day, or more, or even for a month, or a year, the cloud stood still, the people was, as it were, tied to the spot. The old interpreter [2] has not badly rendered it, "The children of Israel were upon the watch;" since day and night they anxiously expected the time when God would command them to move forward. The last verse of the chapter confirms this sense, where it is again added, that "they kept the charge of the Lord at His mouth by the hand of Moses:" whence it appears that Moses was God's interpreter, so that they might set forth on their march whenever the cloud being lifted up pointed out to them the way. Nor can it be doubted but that it preceded them; so that they might know in what direction God would have them proceed, and whither they were to go. Moreover, it must be observed that in both respects it is counted worthy of praise in the people, that they should either journey, or continue where they were, at God's command. Thus is that absurd activity condemned which engages itself in endless work; as if men could only obey God by turmoil. Whereas it is sometimes no less a virtue to rest, when it so pleases God. [3]

"The sense of the passage (he says) is, that the Israelites set up the holy tabernacle, and observed the holy rites, if they were detained for many days in one place; but if for a short time only, the tabernacle was not set up. Whether this was to be the case or not was indicated to them by Moses, according to ver. 23."

And when the cloud tarried long upon the tabernacle many days, then the children of Israel kept the (i) charge of the LORD, and journeyed not.
(i) They waited when the Lord would signify either their departure, or their abode by the cloud.

And when the cloud tarried long upon the tabernacle many days,.... Or years, for days are sometimes put for years, and in some places the cloud tarried several years; or however, if it stayed but a month or a year in any place, as in Numbers 9:22,
then the children of Israel kept the charge of the Lord, and journeyed not; they not only kept watching when it would move, or set sentinels for that purpose to observe it, but they kept the charge, order, or commandment, which the tarrying of the cloud was a token of, and did not attempt to proceed in their journey until they had an intimation so to do by its motion; and all this while, likewise, the tabernacle being up, they observed all the precepts and ordinances of the Lord in the service of it.

when the cloud tarried long upon the tabernacle, . . . then Israel kept the charge of the Lord, and journeyed not--A desert life has its attractions, and constant movements create a passionate love of change. Many incidents show that the Israelites had strongly imbibed this nomad habit and were desirous of hastening to Canaan. But still the phases of the cloud indicated the command of God: and whatsoever irksomeness they might have felt in remaining long stationary in camp, "when the cloud tarried upon the tabernacle many days, they kept the charge of the Lord, and journeyed not." Happy for them had they always exhibited this spirit of obedience! and happy for all if, through the wilderness of this world, we implicitly follow the leadings of God's Providence and the directions of God's Word!

The charge - That is, the command of God, that they should stay as long as the cloud stayed.
