A voice was heard; rather, is heard. It is a participle, indicating the continuance of the action. In Ramah. In the neighbourhood of which town Rachel was buried, according to 1 Samuel 10:2 ("the city" where Samuel and Saul were—1 Samuel 9:25—appears to have been Ramah).
Rachel weeping for her children. Rachel ("Rahel" is only a Germanizing way of writing the name), being the ancestress of the three tribes, Ephraim, Manasseh, and Benjamin, is represented as feeling like a mother for all the tribes connected with those three.
Her "weeping" is no mere figure of speech. Jeremiah believes that the patriarchs and holy men of old continue to feel an interest in the fortunes of their descendants (comp. Isaiah 63:16).
