And Hezekiah sent to all Israel and Judah,.... Sent messengers to them, not only to the subjects of his own kingdom, Judah, but to all the Israelites that dwelt in it, who were come thither for the sake of religion, and the worship of God: and wrote letters also to Ephraim and Manasseh; which are put for all the ten tribes, as appears from Ch2 30:10 and are distinguished from Israel in the preceding clause: that they should come to the house of the Lord at Jerusalem; not that he laid his commands upon them to come, they not being his subjects, namely, those of the ten tribes; but he hereby admonished them of their duty, and gave them a kind invitation, signifying the doors of the temple were open for them, and they were welcome to come thither: to keep the passover unto the Lord God of Israel; to the glory of his name, who was the common Lord of them all, and whose command it was to keep the passover, and that at Jerusalem, and nowhere else, see Deu 16:1.
