Which part of this excerpt from Homer’s Odyssey depicts Ulysses revealing his true identity to his faithful servants Eumaeus and Philaetius?

He saw their secret souls, and thus began:
"Those vows the gods accord; behold the man!
Your own Ulysses! twice ten years detain'd
By woes and wanderings from this hapless land:
At length he comes; but comes despised, unknown,
And finding faithful you, and you alone.
All else have cast him from their very thought,
E'en in their wishes and their prayers forgot!
Hear then, my friends: If Jove this arm succeed,
And give yon impious revellers to bleed,
My care shall be to bless your future lives
With large possessions and with faithful wives;
Fast by my palace shall your domes ascend,
And each on young Telemachus attend,
And each be call'd his brother and my friend.
To give you firmer faith, now trust your eye;
Lo! the broad scar indented on my thigh,
When with Autolycus' sons, of yore,
On Parnass' top I chased the tusky boar."
His ragged vest then drawn aside disclosed
The sign conspicuous, and the scar exposed:
Eager they view'd, with joy they stood amazed
With tearful eyes o'er all their master gazed:
Around his neck their longing arms they cast,
His head, his shoulders, and his knees embraced;
Tears followed tears; no word was in their power;
In solemn silence fell the kindly shower.
The king too weeps, the king too grasps their hands;
And moveless, as a marble fountain, stands.
