Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the LORD, till he come and rain righteousness on you. (Hosea 10:12)
Till he come; seek with patience and faith until he doth, as certainly he will, come; for this passage is a virtual or implicit promise that God will come to them if they seek him, i.e. he will bless, favour, and love them; in these he will appear to them, which is his coming to them.
Rain righteousness; plentifully pour out the fruits of his own goodness and mercy which he hath promised, and, having promised, it is a righteous thing they should be given according to promise; thus the mercies of God to us are his righteousness to us.
Upon you, who repent and obey his counsel by his prophets.
