The "Zidkijah" of this passage is probably the same as "Zadok" Nehemiah 13:13. "Zadok" is expressly called "the scribe," and it was probably as the scribe who drew up the document that "Zidkijah" signed it immediately after Nehemiah.

Now those that sealed - Four classes here seal. Nehemiah first, as their governor. And after him, secondly, The priests, Nehemiah 10:2-8. Thirdly, The Levites, Nehemiah 10:9-13. Fourthly, The chiefs of the people, Nehemiah 10:14-27.
It is strange that, among all these, we hear nothing of Ezra, nor of the high priest Eliashib. Nor are any of the prophets mentioned, though there must have been some of them at Jerusalem at this time.
The whole of this chapter, the two first verses excepted, is wanting in the Arabic; the word Pashur of the third verse is retained; and the rest of the chapter is summed up in these words, and the rest of their assembly.

Now those that sealed were,.... That sealed the covenant, made Nehemiah 9:38.
Nehemiah the Tirshatha, the son of Hachaliah; the governor of the Jews:
and Zidkijah; who seems also to have been a prince, since, without, it could not be said it was sealed by their princes, Nehemiah 9:38 though some think both these were priests, and then the princes must be supposed to be among the chief of the people, Nehemiah 10:14, from hence to the end of the twenty seventh their names follow; the names of the priests, Nehemiah 10:2, who were in all twenty one; no mention is made either of Eliashib the high priest, nor of Ezra the priest and scribe; some think the former had not behaved well in his office, and that the latter was either sick, or returned to Babylon, or however hindered by some providence or another, since we hear of him both a little before and after, Nehemiah 8:2 then the names of the Levites, Nehemiah 10:9, in all seventeen, most of which we have met with in this book before; next follow the names of the chief of the people, Nehemiah 10:14, their number in all forty four; and their names may be observed in the list of those that came out of Babylon with Zerubbabel; the whole number of those that sealed, princes, priests, Levites, and chief of the people, were eighty four.

Conversion is separating from the course and custom of this world, devoting ourselves to the conduct directed by the word of God. When we bind ourselves to do the commandments of God, it is to do all his commandments, and to look to him as the Lord, and our Lord.

THE NAMES OF THOSE WHO SEALED THE COVENANT. (Nehemiah. 10:1-27)
Nehemiah, the Tirshatha--His name was placed first in the roll on account of his high official rank, as deputy of the Persian monarch. All classes were included in the subscription; but the people were represented by their elders (Nehemiah 10:14), as it would have been impossible for every one in the country to have been admitted to the sealing.
Those who were not present at the sealing ratified the covenant by giving their assent, either in words or by lifting up their hands, and bound themselves, by a solemn oath, to walk in God's law, imprecating a curse upon themselves in the event of their violating it.

(10:2)
A covenant made (vv. 1-32), and an engagement entered into, to furnish what was needed for the maintenance of the temple, its services, and ministers (Nehemiah 10:33-39). - Vv. 1-28. For the purpose of giving a lasting influence to this day of prayer and fasting, the assembled people, after the confession of sin (given in Nehemiah 9), entered into a written agreement, by which they bound themselves by an oath to separate from the heathen, and to keep the commandments and ordinances of God, - a document being prepared for this purpose, and sealed by the heads of their different houses.
And because of all this we make and write a sure covenant; and our princes, Levites, and priests sign the sealed (document). בּכל־זאת does not mean post omne hoc, after all that we have done this day (Schmid, Bertheau, and others); still less, in omni hoc malo, quod nobis obtigerat (Rashi, Aben Ezra), but upon all this, i.e., upon the foundation of the preceding act of prayer and penitence, we made אמנה, i.e., a settlement, a sure agreement (the word recurs Nehemiah 11:23); hence כּרת is used as with בּרית, Nehemiah 9:8. אמנה may again be taken as the object of כּתבים, we write it; החתוּם ועל be understood as "our princes sealed." החתוּם is the sealed document; comp. Jeremiah 22:11, Jeremiah 22:14. החתוּם על means literally, Upon the sealed document were our princes, etc.; that is, our princes sealed or signed it. Signing was effected by making an impression with a seal bearing a name; hence originated the idiom החתוּם על אשׁר, "he who was upon the sealed document," meaning he who had signed the document by sealing it. By this derived signification is the plural חחתוּמים על (Nehemiah 10:2), "they who were upon the document," explained: they who had signed or sealed the document.

Sealed - Both in their own names, and in the name of all the rest. It may seem strange that Ezra doth not appear among them. But that might be because he was prevented, by some sickness, or other extraordinary impediment. It is true, we meet with Ezra after this, at the dedication of the wall of Jerusalem, Nehemiah 12:36, and therefore he was then freed from this impediment, whatsoever it was.
