Exodus 32 1-24: It has been theorised that the golden calf wasn't so much an idol intended to replace the true God; Rather, it was created as a stand-in while Moses was away, or more accurately, a replacement since the people thought Moses had up and left. We do the same thing today with certain preachers and other religious leaders.
Exodus 34 21: "six days thou shalt work but on the seventh thou shalt rest in earing and harvest thou shalt rest"
This verse reminds us that we are to keep God's commandments, even when it doesn't seem "convenient."
Exodus 35 30 and 31: "and Moses said unto the children of Israel see the Lord hath called by name Bezaleel the son of Uri the son of Hur of the tribe of Judah and He hath filled him with the Spirit of God in wisdom in understanding and in knowledge and in all manner of workmanship"
I find it amazing that God just put the knowledge of craftsmanship into Bezaleel's mind. Praise God!
