covered, litter, tortoise

“Litter” From Boyd’s Bible Dictionary:

(bed). Covered couch or chair, carried by men or animals (Isa. 66:20). “Wagons” (Num. 7:3).

“Tortoise” From Boyd’s Bible Dictionary:

(twisted-foot). A faulty rendering. The Septuagint has “land-crocodile,” and doubtless one of the large lizard species is meant (Lev. 11:29).

“Litter” From Concise Bible Dictionary:

Sedan or light coach, mentioned among the various means by which the Jews will be conveyed to the promised land (Isa. 66:20).

“Tortoise, tsab” From Concise Bible Dictionary:

One of the unclean animals. The Hebrew word is supposed to refer to a lizard, but to what species is not known: perhaps the dhab of the Arabs, a large lizard. The RV has “great lizard.” The tortoise, however, is common in Palestine (Lev. 11:29).
