“Say you to your brothers, Ammi; and to your sisters, Ruhamah.”
Note how the names of the three children have been repeated, combining Hosea 1:11, with its mention of Jezreel, and this verse with the mention of Ammi and Ruhama. The positive note brought out here would serve to confirm that ‘Jezreel' in Hosea 1:11 is connected with restoration. And the consequence of ‘the day of Jezreel' will be that Jezreel will be able to say to all his brothers, ‘My People' and to all his sisters, ‘Beloved'. The names of the children of portent will be changed by dropping the negative, and the new names will be given to the whole family as representing the whole nation, because God's attitude towards His people will have changed. They will again be His people and beloved.
Alternately the speaker may be seen as the prophet Hosea, but it makes little difference to the sense.
