kum'-ber, (katargeo, "to make idle," perispaomai, "to be drawn about," in mind "to be distracted"): Spoken of the barren fig tree in the parable: "Cut it down; why doth it also cumber (block up, make unproductive) the ground?" (Luke 13:7). Cumbered means to be over-occupied with cares or business, distracted: "But Martha was cumbered about much serving" (Luke 10:40). The word cumbrance occurs only in Deuteronomy 1:12: "How can I myself alone bear your cumbrance?" (Torach, "an encumbrance," "a burden"). Compare Isaiah 1:14, where the Revised Version, margin has "cumbrance," the Revised Version (British and American) "trouble."
