Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take {d} another stick, and write upon it, For Joseph, the stick of Ephraim, and for all the house of Israel his companions:

(d) Which signifies the joining together of the two houses of Israel and Judah.

Wesley's Notes

37:16 One stick - A writing tablet or a tally, such as is fit to be written upon. His companions - Benjamin and part of Levi, who kept with the tribe of Judah. Ephraim - Ephraim was the most considerable tribe in the kingdom of Israel, when divided from the other two. The house of Israel - The other nine tribes, who continued with Ephraim.

Jamieson-Fausset-Brown Bible Commentary

16. stick-alluding to Nu 17:2, the tribal rod. The union of the two rods was a prophecy in action of the brotherly union which is to reunite the ten tribes and Judah. As their severance under Jeroboam was fraught with the greatest evil to the covenant-people, so the first result of both being joined by the spirit of life to God is that they become joined to one another under the one covenant King, Messiah-David.

Judah, and . children of Israel his companions-that is, Judah and, besides Benjamin and Levi, those who had joined themselves to him of Ephraim, Manasseh, Simeon, Asher, Zebulun, Issachar, as having the temple and lawful priesthood in his borders (2Ch 11:12, 13, 16; 15:9; 30:11, 18). The latter became identified with Judah after the carrying away of the ten tribes, and returned with Judah from Babylon, and so shall be associated with that tribe at the future restoration.

For Joseph, the stick of Ephraim-Ephraim's posterity took the lead, not only of the other descendants of Joseph (compare Eze 37:19), but of the ten tribes of Israel. For four hundred years, during the period of the judges, with Manasseh and Benjamin, its dependent tribes, it had formerly taken the lead: Shiloh was its religious capital; Shechem, its civil capital. God had transferred the birthright from Reuben (for dishonoring his father's bed) to Joseph, whose representative, Ephraim, though the younger, was made (Ge 48:19; 1Ch 5:1). From its pre-eminence "Israel" is attached to it as "companions." The "all" in this case, not in that of Judah, which has only attached as "companions" "the children of Israel" (that is, some of them, namely, those who followed the fortunes of Judah), implies that the bulk of the ten tribes did not return at the restoration from Babylon, but are distinct from Judah, until the coming union with it at the restoration.

Matthew Henry's Concise Commentary

37:15-28 This emblem was to show the people, that the Lord would unite Judah and Israel. Christ is the true David, Israel's King of old; and those whom he makes willing in the day of his power, he makes to walk in his judgments, and to keep his statutes. Events yet to come will further explain this prophecy. Nothing has more hindered the success of the gospel than divisions. Let us study to keep the unity of the Spirit in the bond of peace; let us seek for Divine grace to keep us from detestable things; and let us pray that all nations may be obedient and happy subjects of the Son of David, that the Lord may be our God, and we may be his people for evermore.
