Exodus 25:2; Exodus 35:21; Exodus 35:29
"Tell the Israelites to bring me an offering. You are to receive the offering for me from each man whose heart prompts him to give.
and everyone who was willing and whose heart moved him came and brought an offering to the LORD for the work on the Tent of Meeting, for all its service, and for the sacred garments.
All the Israelite men and women who were willing brought to the LORD freewill offerings for all the work the LORD through Moses had commanded them to do.
