Commentary on Exodus 35:4-19

(Read Exodus 35:4-19)

The tabernacle was to be dedicated to the honour of God, and used in his service; and therefore what was brought for it, was an offering to the Lord. The rule is, Whosoever is of a willing heart, let him bring. All that were skilful must work. God dispenses his gifts; and as every man hath received, so he must minister, 1 Corinthians 12:7-21.
