1. The title the prophet gives them in God's name: O my threshing, and the corn of my floor! The prophet calls them his, because they were his countrymen, and such as he had a particular interest in and concern for; but he speaks it as from God, and directs his speech to those that were Israelites indeed, the faithful in the land. Note, (1.) The church is God's floor, in which the most valuable fruits and products of this earth are, as it were, gathered together and laid up. (2.) True believers are the corn of God's floor. Hypocrites are but as the chaff and straw, which take up a great deal of room, but are of small value, with which the wheat is now mixed, but from which it shall be shortly and for ever separated. (3.) The corn of God's floor must expect to be threshed by afflictions and persecutions. God's Israel of old was afflicted from her youth, often under the plougher's plough (Ps. cxxix. 3) and the thresher's flail. (4.) Even then God owns it for his threshing; it is his still; nay, the threshing of it is by his appointment, and under his restraint and direction. The threshers could have no power against it but what was given them from above.
