Which phrase contains a metaphor?

Thou therefore take my brand Excalibur,

Which was my pride: for thou rememberest how

In those old days, one summer noon, an arm

Rose up from out the bosom of the lake,

Clothed in white samite, mystic, wonderful,

Holding the sword-and how I row'd across

And took it, and have worn it, like a king:

And, wheresoever I am sung or told

In aftertime, this also shall be known

"take my brand Excalibur, / Which was my pride"

"Rose up from out the bosom of the lake"

"and have worn it, like a king"
