Looking up for the blessing.
The interests of the dependent classes, "the Levite, the stranger, the fatherless, and the widow," being considered and secured by the tithing of the third year, the Jew was directed then to look up for the Divine blessing on the land. The tithe was first paid, and then the blessing sought.
I. SYSTEMATIC BENEFICENCE SHOULD BE THE PRELIMINARY OF SUPPLICATION FOR BLESSING, AND NOT CONDITIONED UPON IT. There is a temptation to make liberality a matter of speculation, to vow a certain portion if a certain blessing is conferred. Now, this may be all very well regarding what is beyond a tithe, but the tithe is a settled proportion to be promptly and gratefully paid, and the blessing can then be honestly asked when the debt to God has been discharged.
II. THE TRULY LIBERAL WILL LOOK FOR SPIRITUAL BLESSING FOR HIS COUNTRY, AND NOT BE CONTENT WITH TEMPORAL. In fact, it was revival, as we should now call it, that the Jew after his tithing sought. And systematic beneficence should be regarded as the indispensable preliminary of revival, if Malachi 3:10 has any meaning. It is manifest that illiberality may hinder spiritual blessing, and consequently liberality should be fostered as the manifest test of sincerity regarding blessing. If one is not willing to pay his share that every hindrance of blessing may be removed, he cannot be in earnest about it.
III. MOSES, AS THE MEDIATOR, GUARANTEES THE COVENANT BLESSINGS TO THE COVENANT-KEEPING PEOPLE. God had brought Israel out of Egypt, and was about to introduce them to the land of promise, that they might prove his "peculiar people," and be "high above all nations which he hath made, in praise, and in name, and in honor," and above all, be "an holy people." This was his covenant engagement. Hence Moses urges them to keep the commandments God has given them with all their heart and soul, and they shall find how faithful God is.
Obedience is consequently to be the manifestation of their faith in God as "Faithful Promiser." If he gave the blessings in all their fullness first, faith would have no room to grow, and his people would be able to live well enough by sight. But when they are asked to obey and be blessed in and through their obedience, faith has its beautiful sphere.—R.M.E.
