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)).
