1 After the imperative, the cohortative with prefixed vav (ו) indicates purpose/result.
2 The expression “in the future” (אַחֲרִית הַיָּמִים, ’akharit hayyamim, “in the end of days”) is found most frequently in prophetic passages; it may refer to the end of the age, the eschaton, or to the distant future. The contents of some of the sayings in this chapter stretch from the immediate circumstances to the time of the settlement in the land to the coming of Messiah. There is a great deal of literature on this chapter, including among others C. Armerding, “The Last Words of Jacob: Genesis 49,” 112 (1955): ; H. Pehlke, “An Exegetical and Theological Study of Genesis 49:1–28” (Th.D. dissertation, Dallas Theological Seminary, 1985); and B. Vawter, “The Canaanite Background of Genesis 49,” 17 (1955): 1–18.
