1 Samuel 18:4

And Jonathan stripped himself of the robe that was upon him, and gave it to David.

David invested with royal robes

From the days of Homer and the Trojan wars downwards, this has been the method employed by Orientals to denote the bestowment of dignity and distinction. Not more eagerly coveted is the Order of the Garter, or Bath, or Thistle among ourselves than in ancient times was the gift of royal robes. Any portion, indeed, of a king’s wardrobe or jewel box was greatly prized; but the voluntary donation of dress, and more particularly in the act of being worn, rendered the tribute doubly valuable. Whenever this latter occurred the cherished memento was transmitted as an heirloom from sire to son. It was equivalent to a patent of nobility. (J. R. Macduff, D. D.)

We find in Homer a minute enumeration of the armour Ulysses received in a gift from Meriones, and in the story of Nisus and Euryalus, in the IX OEneid of Virgil, there occurs a duplicate picture of that presented to us in the tent of Saul. (J. R. Macduff, D. D.)
