John Gill Commentary 1 Chronicles 26:28

"And all that Samuel the seer, and Saul the son of Kish, and Abner the son of Ner, and Joab the son of Zeruiah, had dedicated, whosoever had dedicated anything, it was under the hand of Shelomoth, and of his brethren." — 1 Chronicles 26:28 (ASV)

And all that Samuel the seer
Or prophet, won in battle with the Philistines:

and Saul the son of Kish ;
in his wars with the Moabites, Edomites, Amalekites, and Philistines:

and Abner the son of Ner :
the general of his army, who as such had his share in the spoils:

and Joab the son of Zeruiah ;
the general of David's army, who fought with the Ammonites, Syrians, and others; all of whom

had dedicated
more or less towards the building of the temple, and the support of it, it being known by them all that God would have a place to put his name in:

[and] whosoever had dedicated anything, it was under the hand of
Shelomith, and of his brethren :
this man had a great trust committed to him, with his brethren; some, before mentioned, are said to be over the treasures, some over one part, and some over another; but this man was over all of them, he had the superintendency of the whole.
