plank: Thick beams or pieces of wood, for which several Hebrew words are used. The Revised Version (British and American) changes "planks" (of fir) into "boards" in1Ki 6:15, and in a few instances substitutes "planks" where the King James Version has "boards" (Ex 27:8;38:7, the altar;Eze 27:5). So in the New Testament inAc 27:44, for sanis.
