מילון על ראש השנה 62:7

Though the pigeon offerings have ceased,¹The literal translation of the word רֶבַע is a quarter. In the time of the Temple a poor man was permitted to bring doves or young pigeons which were worth a quarter of a dinar for his offerings. though the tent of His dwelling is now empty, we need not lose hope for we have the merit of our old father.²Abraham.
