How was greed demonstrated by Gehazi?

2Ksngs 5:16 – 27:

After the cleansing of Naaman at River Jordan, he then returned to the man of
God with all his company,
He then presented gifts to Elisha the prophet
which he refused even after persuasion,
But when Naaman had gone a short
dista’nce, Gehazi, Elisha’s servant, followed him.
When Naaman saw him, he
alighted from his chariot to meet him.
He asked if all was well, and Gehazi
said that his master sent him to collect the gift,
He then collected the
two talents of silver in two bags and some garments,
He put them on two
of his servants to carry them for Gehazi.
And when they came close home
he collected the items from them and sent the men away,
He then hid them
in his room,
Later, his master Elisha asked him “where have you been
Gehazi?”
He lied that-he went nowhere,
His master said he was
with him in the spirit and he saw the things he collected from Naaman.
He, therefore, cursed him that the leprosy of Naaman would cleave to him and
his descendants forever,
And it was so/He became leprous immediately.
