Among the Jews there is a Sabbath liturgy that says:
By the mouth of the upright You are praised;
By the words of the righteous You are blessed;
By the tongue of the faithful You are extolled
And within the holy You are sanctified.’
The methods of expression are mouth, words, tongue and within. The identification is the upright, righteous, faithful and holy. The result is praise, blessing, exaltation (to praise highly), and sanctification.
Those who reach the lowest stage of devotion are called the upright; their worship is expressed through the mouth. Higher than these are the righteous, where their worship is not expressed through the mouth but in the mere movement of the lips. Higher than these are the faithful; their worship is on the tongue; it does not even pass the lips. The highest kind of worship is the holy one; their worship is hidden and concealed within them and is apparent only to Him who knows all secrets. So say the old Rabbis.
“You shall worship the Lord your God, and serve him only.” Jesus
