Easton's 1897 Bible Dictionary:

Carriage
   In the Authorized Version this word is found as the rendering of
   many different words. In Judg. 18:21 it means valuables, wealth,
   or booty. In Isa. 46:1 (R.V., "the things that ye carried
   about") the word means a load for a beast of burden. In 1 Sam.
   17:22 and Isa. 10:28 it is the rendering of a word ("stuff" in 1
   Sam. 10:22) meaning implements, equipments, baggage. The phrase
   in Acts 21:15, "We took up our carriages," means properly, "We
   packed up our baggage," as in the Revised Version.
