18 Heb “[with] a mighty struggle I have struggled with my sister, also I have prevailed.” The phrase “mighty struggle” reads literally “struggles of God.” The plural participle “struggles” reflects the ongoing nature of the struggle, while the divine name is used here idiomatically to emphasize the intensity of the struggle. See J. Skinner, Genesis (), .
19 The name Naphtali (נַפְתָּלִי, naftali) must mean something like “my struggle” in view of the statement Rachel made in the preceding clause. The name plays on this earlier statement, “[with] a mighty struggle I have struggled with my sister.”
