It is likely that during the unsettled times of the Judges Judges 21:25 the attendance of Israelites at the three Festivals Exodus 34:23; Deuteronomy 16:16 fell into desuetude or great irregularity, and this one feast (see the marginal reference), which may have coincided with the Feast of Pentecost or tabernacles, may have been substituted for them.
The Lord of Hosts - This title of Yahweh which, with some variations, is found upward of 260 times in the Old Testament, occurs here for the first time. The meaning of the word “hosts” is doubtless the same as that of “army” Daniel 4:35 and includes all the myriads of holy Angels who people the celestial spheres 1 Kings 22:19. It is probably with reference to the idolatrous worship of the Host of heaven that the title the “Lord of Hosts” was given to the true God, as asserting His universal supremacy (see Nehemiah 9:6). In the New Testament the phrase only occurs once James 5:4.
And the two sons ... - It should be, “and there the two sons of Eli, Hophni and Phinehas, were priests to the Lord,” i. e. performed the functions of priests, in the old age of Eli 1 Samuel 4:18, who is represented 1 Samuel 1:9 as sitting on a seat in the temple. The reading of the Greek Version “Eli was there, and his two sons, Hophni and Phinehas, priests of the Lord,” is quite unnecessary, and indeed destroys the sense. The information here given concerning the sons of Eli is followed up in 1 Samuel 2:12 ff.
