1 Samuel 1:3

To worship in Shiloh Where the tabernacle now was, and where all sacrifices were to be offered. Hither all the males were bound to resort at the three great annual feasts, (Deuteronomy 16:16,) and not to appear before the Lord empty. Accordingly Elkanah not only worshipped God with prayers and thanksgivings, but offered such sacrifices as were suitable to the festival. Not that he sacrificed in his own person, which the Levites were not permitted to do, but by the priests. Hophni and Phinehas were there Or, were the priests of the Lord there, under their father Eli, who is generally conceived to have been the high-priest, but being very old and infirm, his sons ministered in his stead. This is the first time in Scripture that God is called the Lord of hosts or armies. Probably Samuel was the first who used this title of God, for the comfort of Israel, at the time when their armies were few and feeble, and those of their enemies many and mighty.
