Boyd’s Bible Dictionary:
(car). Baggage (Judg. 18:21; Isa. 10:28; 46:1; Acts 21:15).
Concise Bible Dictionary:
This does not appear to be ever used in the scriptures in the modern sense of the word, but signifies “the thing carried,” “baggage” (Judg. 18:21; 1 Sam. 17:22; Isa. 10:28; Acts 21:15). The meaning in Isaiah 46:1 is probably that the idols which were once “carried” with joy in festal processions (compare Amos 5:26) are now “lifted up as loads” to be carried on beasts of burden.
