'Brethren' in the Bible

“[Hosea,] say to your brothers, ‘Ammi (you are my people),’ and to your sisters, ‘Ruhamah (you have been pitied and have obtained mercy).’

For though he flourishes among the reeds (his fellow tribes),An east wind (Assyria) will come,The breath of the Lord rising from the desert;And Ephraim’s spring will become dryAnd his fountain will be dried up.Assyria will plunder his treasury of every precious object.
