The Lord's Thigh

See Genesis 24:2, 9; 49:10; Psalm 45:3; Revelation 19:16. Compare Isaiah 63:1-6.

The Greek term that's rendered "thigh" is μηρός. See Rogers and Rogers, page 647.

Thigh could refer to the "bodily nature" that the Logos assumes (Edmondo Lupieri, A Commentary on the Apocalypse of John, 306). Names, attributes and dedications were traditionally inscribed on the legs or garments of those who worshiped gods in the Hellenistic sanctuary (idem., 307). The term could be alluding to military gear (ibid.).

For more on Greek statues with names on the thigh, see Aune, Revelation, 52C:1062.

Grant Osborne:

Fourth, the rider on the white horse (19:16) has a name written ἐπὶ τὸ ἱμάτιον καὶ ἐπὶ τὸν μηρὸν αὐτοῦ (epi to himation kai epi ton mēron autou, on his garment at his thigh), which could refer to two places, but most agree (e.g., Beckwith, Ladd, Mounce, Beale) that it is “on his robe, namely [epexegetical καί] his thigh.” In other words, the name is written on that part of his tunic that covered his thigh, the place where his sword would rest and where it would be conspicuous on a mounted warrior.

Osborne also mentions Charles.
