Exodus 25:21 KJV
And thou shalt put the mercy seat above upon the ark; and in the ark thou shalt put the testimony that I shall give thee.
This verse as well as verse 16 calls the two tables comprising the Ten Commandments as given to Moses by God, "the testimony that I shall give thee." Verse 22 alludes to the same.
There are, I suppose, thousands of testimonies in the world.
· Men have testimonies
· Nations have testimonies
· Regions have testimonies
· Political parties have testimonies
· Religions have testimonies
It is the result of their character and of their record.
God gave Moses His testimony because this was the nature of the character God desired them to have. His was a testimony that, if Israel would embrace it, would give them a record unique to anyone in the world. It is a testimony that has been accepted (if not altogether obeyed) by every civilized people since. His testimony influences governments, leaders and individuals around the world.
We may build our own record, our own testimony but the wisest of us will accept the one that God has given us.
