Charles Ellicott Commentary 1 Chronicles 29:3

"Moreover also, because I have set my affection on the house of my God, seeing that I have a treasure of mine own of gold and silver, I give it unto the house of my God, over and above all that I have prepared for the holy house," — 1 Chronicles 29:3 (ASV)

I have set my affection to the house. — 1 Chronicles 28:4 (he liked, râçâh: Psalms 26:8).

I have of mine own proper good, of gold and silver. — I have a personal property in gold and silver. For the word sĕgullâh, peculium, see Exodus 19:5.

I have given — i.e., I give (1 Chronicles 21:23).

Over and above (lĕma‘lâh). — 1 Chronicles 22:5.

All that I have prepared. — The Hebrew again omits the relative. (Compare to 1 Chronicles 15:12.)
