I think there's an allusion.
You must take in consideration Mark 14:52 and Amos 2:16 in their context.
And what can we read in Mark 14 ?
From Mark 14:
10 Then Judas Iscariot, one of the Twelve, went to the chief priests
to betray Jesus to them.
11 They were delighted to hear this and
promised to give him money (ἀργύριον δοῦναι)
42 Rise! Let us go! Here
comes my betrayer!”
43 Just as he was speaking, Judas, one of the
Twelve, appeared. With him was a crowd armed with swords and clubs,
sent from the chief priests, the teachers of the law, and the elders.
51 A young man, wearing nothing but a linen garment, was following
Jesus. When they seized him,
52 he fled naked (γυμνὸς), leaving his garment behind.
Same in Amos 2 :
6 This is what the Lord says: “For three sins of Israel, even for
four, I will not relent. They sell the innocent for silver, (ἀργυρίου
δίκαιον) and the needy for a pair of sandals.
16 And he who is
courageous among the mighty shall flee away naked (γυμνὸς) on that
day, says the Lord.
So basically, i don’t think it can be a coincidence that both Mark and Amos wrote about the righteous being sold for money and the naked man flying away.
In the same context respectively.
If this is a coincidence, it would be a great one.
