¹ tn The meaning of the Hebrew word מְכֵרָה (mÿkherah) is uncertain. It has been rendered (1) “habitations”; (2) “merchandise”; (3) “counsels”; (4) “swords”; (5) “wedding feasts.” If it is from the verb כָּרַת (karat) and formed after noun patterns for instruments and tools (maqtil, miqtil form), then it would refer to “knives.” Since the verb is used in Exod 4:25 for circumcision, the idea would be “their circumcision knives,” an allusion to the events of Gen 34 (see M. J. Dahood, “‘MKRTYHM’ in Genesis 49,5,” CBQ 23 [1961]: 54-56). Another explanation also connects the word to the events of Gen 34 as a reference to the intended “wedding feast” for Dinah which could take place only after the men of Shechem were circumcised (see D. W. Young, “A Ghost Word in the Testament of Jacob (Gen 49:5)?” JBL 100 [1981]: 335-422).
