Deuteronomy 27:17

“You shall not move your neighbor’s boundary mark, which the ancestors have set, in your inheritance which you will inherit in the land that Yahweh your God gives you to possess.

“Some move the boundaries; They seize and devour flocks.

Do not move the ancient boundary Which your fathers made.

“Indeed all Israel has trespassed against Your law, even turning aside, not listening to Your voice; so the curse has been poured out on us, along with the oath which is written in the law of Moses the servant of God, for we have sinned against Him.

The princes of Judah have become like those who move a boundary; On them I will pour out My wrath like water.

Otherwise if you bless in the spirit only, how will the one who fills the place of the uninformed say the “Amen” at your giving of thanks, since he does not know what you are saying?
