Genesis 49:17
יְהִי דָן נָחָשׁ עֲלֵי דֶרֶךְ שְׁפִיפֹן עֲלֵי אֹרַח הַ נֹּשֵׁךְ עִקְּבֵי סוּס וַ יִּפֹּל רֹכְבֹו אָחֹור
Judge is becoming a serpent upon the road, a stinger1370 upon the caravan-way, the One-who-bites the heels of the horse, and his rider is falling the backside.
| 1370 | Strong’s #8207, shephiphon. This word is only found here. Traditionally thought to be a “horned viper” the root is apparently shaphaph to pierce, wound, bite. It is similar to shuph used in Gen 3:15, “he is gaping-upon [biting] the heel” |
