The sacrifices and rituals that are part of the Tabernacle and Temple are known generically as avodah, service. Avodah is at the core of what it means to be Israel. This is the same word for working in the fields as well as for worshipping. Avodah means work, worship, and service. The various meanings of the Hebrew word imply that our work and our worship can be a seamless way of living. 

The root of this word shows up in Genesis 2:5 in relation to working the ground. 

And every plant of the field before it was in the earth, and every herb of the field before it grew: for the LORD God had not caused it to rain upon the earth, and there was not a man to till (avodah) the ground.

It shows up in Exodus 8:1 in relation to worshipping God. 

“This is what the LORD says: Let my people go, so that they may worship (avodah) me.” 

It’s what Joshua declared “As for me and my house, we will avodah the LORD!” We will work for, and worship, the Lord.
