The hooks, chapiters, and fillets here spoken of belonged to the pillars of the court. See Exodus 27:10, Exodus 27:17.
Matthew Henry
Concise Bible Commentary
The foundation of massy pieces of silver showed the solidity and purity of the truth upon which the church is founded. Let us regard the Lord Jesus Christ while reading of the furniture of the tabernacle. While looking at the altar of burnt-offering, let us see Jesus. In him, his righteousness, and salvation, is a full and sufficient offering for sin. In the laver of regeneration, by his Holy Spirit, let our souls be washed, and they shall be clean; and as the people offered willingly, so may our souls be made willing. Let us be ready to part with any thing, and count all but loss to win Christ.
