It means the others are direct quotes from the bible but the last one is not a direct quote but a statement based on their interpretation of Matthew 25 - and boy do they self-servingly twist the meaning of Matthew 25! That text is clearly about charitable acts toward christians, but they twist it to mean helping the Watchtower spread its propaganda from house to house.
Yes. It will be interesting to see what they say in this part of the talk. They should have made it: Those that help "the least" of Christs brothers
..because that is the point of the verse...
10:20 Symposium:Who Will Inherit God’s Kingdom?
Those “Who Are Poor” (Luke6:20; Matthew5:3)
Those Who “Become as Young Children” (Matthew18:2-4)
Those “Persecuted for Righteousness’ Sake” (Matthew5:10)
Those Who Help Christ’s Brothers (Matthew25:34)
Then the King will say to those on his right: ‘Come, you who have been blessed by my Father, inherit the Kingdom prepared for you from the founding of the world. 35 For I became hungry and you gave me something to eat; I was thirsty and you gave me something to drink. I was a stranger and you received me hospitably;+ 36 naked* and you clothed me.+ I fell sick and you looked after me. I was in prison and you visited me.’+ 37 Then the righteous ones will answer him with the words: ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink?+ 38 When did we see you a stranger and receive you hospitably, or naked and clothe you? 39 When did we see you sick or in prison and visit you?’ 40 In reply the King will say to them, ‘Truly I say to you, to the extent that you did it to one of the least of these my brothers, you did it to me.’+
Then he will say to those on his left: ‘Go away from me, + you who have been cursed, into the everlasting fire + prepared for the Devil and his angels. + 42 For I became hungry, but you gave me nothing to eat; and I was thirsty, but you gave me nothing to drink. 43 I was a stranger, but you did not receive me hospitably; naked, but you did not clothe me; sick and in prison, but you did not look after me.’ 44 Then they too will answer with the words: ‘Lord, when did we see you hungry or thirsty or a stranger or naked or sick or in prison and did not minister to you?’ 45 Then he will answer them, saying: ‘Truly I say to you, to the extent that you did not do it to one of these least ones, you did not do it to me.’ + 46 These will depart into everlasting cutting-off, * + but the righteous ones into everlasting life.”
