Morrish Bible Dictionary [3]

This does not appear to be ever used in the scriptures in the modern sense of the word, but signifies 'the thing carried,' 'baggage.'  Judges 18:21;  1 Samuel 17:22;  Isaiah 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 (cf.   Amos 5:26 ) are now 'lifted up as loads' to be carried on beasts of burden.

Smith's Bible Dictionary [4]

Carriage. This word signifies what we now call "Baggage". In the margin of  1 Samuel 17:20, and  1 Samuel 26:5-7, and there only, "carriage" is employed in the sense of A Wagon or Cart.

Easton's Bible Dictionary [5]

 Judges 18:21  Isaiah 46:1  1 Samuel 17:22  Isaiah 10:28  1 Samuel 10:22 Acts 21:15

Hastings' Dictionary of the Bible [6]

CARRIAGE . This word is always used in the AV [Note: Authorized Version.] in the literal sense of ‘something carried,’ never in the modern sense of a vehicle used for carrying. Thus   Acts 21:15 ‘we took up our carriages’ (RV [Note: Revised Version.] ‘baggage’).

Holman Bible Dictionary [7]

 Judges 18:21 1 Samuel 17:22 Isaiah 10:28 Isaiah 46:1 Acts 21:15

American Tract Society Bible Dictionary [8]

In the Bible, usually means the baggage which formed the burden of a man of beast,  Acts 21:15 . Once it seems to indicate a circular trench or rampart of baggage, etc., around a camp, /  1 Samuel 17:20 .

International Standard Bible Encyclopedia [9]

kar´ij ( כּלי , kelı̄ , כּבוּדּה , kebhuddāh , נשׂוּאה , nesū'āh  ; ἐπισκευασάμενοι , episkeuasámenoi  ; the Revised Version (British and American) "We took up our baggage"; the American Revised Version, margin "made ready"): One or the other of the above words occurs in six different places and all have been translated in the King James Version by "carriage" in its obsolete meaning ( Judges 18:21;  1 Samuel 17:22 (twice);   Isaiah 10:28;  Isaiah 46:1;  Acts 21:15 ). In the Revised Version (British and American) and the American Standard Revised Version these are translated by the more modern expressions "goods," "baggage," or "the things that you carried." In  1 Samuel 17:20 the King James Version margin"place of the carriage" occurs as the equivalent of "trench." The Hebrew ma'gālāh may mean "the place of wagons" as translated in the Revised Version (British and American), as it is not at all improbable that the encampment was surrounded by the baggage train.
