Flock

Dictionary of Biblical Words:

The fold in John 10 means the Jewish enclosure formed by God’s law and ordinances, out of which the rejected Christ was then leading His sheep, above all, in His death; after which He would form one flock, composed of believing Jews and Gentiles, His “other Sheep which were not of this fold” or Jewish people (ver. 16). One fold is wrong; it should unquestionably be rendered “one flock” as is now well known. There is no longer anything recognized of God as one fold (as Romanism). still less, many folds as Protestantism, but one flock, one shepherd, or as the Apostle puta it, “One body and one Spirit.”

Concise Bible Dictionary:

A term used in the O. T. for Israel as sheep gathered by God as their Shepherd, and called Jehovah's flock (Psa. 77:2020Thou leddest thy people like a flock by the hand of Moses and Aaron. (Psalm 77:20); Psa. 107:4141Yet setteth he the poor on high from affliction, and maketh him families like a flock. (Psalm 107:41); Jer. 13:1717But if ye will not hear it, my soul shall weep in secret places for your pride; and mine eye shall weep sore, and run down with tears, because the Lord's flock is carried away captive. (Jeremiah 13:17)). It is also applied to those of Israel that were gathered to Christ when on earth. To these He added the Gentile believers; and all were united into one flock (not “one fold”), with Christ as the one Shepherd (John 10:1616And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd. (John 10:16)). When the leaders of Israel were to be judged as not caring for the Lord's flock, the prophet speaks of the remnant as the poor of the flock (Zech. 11:7, 117And I will feed the flock of slaughter, even you, O poor of the flock. And I took unto me two staves; the one I called Beauty, and the other I called Bands; and I fed the flock. (Zechariah 11:7)
11And it was broken in that day: and so the poor of the flock that waited upon me knew that it was the word of the Lord. (Zechariah 11:11): Compare Luke 6:2020And he lifted up his eyes on his disciples, and said, Blessed be ye poor: for yours is the kingdom of God. (Luke 6:20)).
