'Testimony' in the Bible

The law of the Lord is perfect (flawless), restoring and refreshing the soul;The statutes of the Lord are reliable and trustworthy, making wise the simple.

For He established a testimony (a specific precept) in JacobAnd appointed a law in Israel,Which He commanded our fathersThat they should teach to their children [the great facts of God’s transactions with Israel],

He established it for a testimony in JosephWhen He went throughout the land of Egypt.I heard the language [of One whom] I did not know, saying,

According to Your steadfast love refresh me and give me life,So that I may keep and obey the testimony of Your mouth.

To which the [twelve] tribes go up, even the tribes of the Lord,[As was decreed as] an ordinance for Israel,To give thanks to the name of the Lord.

“If your children will keep My covenantAnd My testimony which I will teach them,Their children also shall sit upon your throne forever.”
