1st Chronicles 21:1 And Satan stood up against Israel, and provoked David to number Israel. 2 And David said to Joab and to the rulers of the people, Go, number Israel from Beersheba even to Dan; and bring the number of them to me, that I may know it.
[Patriarchs & Prophets pp 747] With a view to extending his conquests among foreign nations, David determined to increase his army by requiring military service from all who were of proper age. To effect this, it became necessary to take a census of the population. It was pride and ambition that prompted this action of the king. The numbering of the people would show the contrast between the weakness of the kingdom when David ascended the throne and its strength and prosperity under his rule.
This would tend still further to foster the already too great self-confidence of both king and people. The Scripture says, “Satan stood up against Israel, and provoked David to number Israel.” The prosperity of Israel under David had been due to the blessing of God rather than to the ability of her king or the strength of her armies. But the increasing of the military resources of the kingdom would give the impression to surrounding nations that Israel's trust was in her armies, and not in the power of Jehovah.
Though the people of Israel were proud of their national greatness, they did not look with favor upon David's plan for so greatly extending the military service. The proposed enrollment caused much dissatisfaction; consequently it was thought necessary to employ the military officers in place of the priests and magistrates, who had formerly taken the census. The object of the undertaking was directly contrary to the principles of a theocracy.
1st Chronicles 21:3 And Joab answered, The Lord make his people an hundred times so many more as they be: but, my lord the king, are they not all my lord's servants? why then doth my lord require this thing? why will he be a cause of trespass to Israel?
May God add His blessing to the study of His word. “Good night” and God bless!
