"Haleluyah! Give praise, O servants of Hashem"
The rabbis explain that when one person praises another, the praise should be in accordance with that person's merit. This is because praise given that is not deserved becomes a reproach. Through a discussion of the title verse, we learn that the name 'Haleluyah' is among the highest kinds of praise to God since it contains both the highest name as well the praise itself. The rest of the verse reveals the name of the praised and those who address the praise. This means that they, the servants of The Creator, praised the place called "the Name of Yah," Malchut. We're then told of the significance of the Yud י in the Hebrew translation of the word let, and its relationship to "the drawing from the most hidden." The discourse then reveals the meaning of the words, "From the rising of the sun to its setting." This alludes to Zeir Anpin, whence the sun shines and Malchut, the place to which Faith is bound.
The wisdom to offer praise to others with purity and in the appropriate measure is awakened in us. The Holy Name of "Haleluyah" and the letter Yud י connect us to lofty levels in the spiritual atmosphere, arousing Light, blessing, and praise throughout our physical world [Malchut]. We are inspired to become worthy of praise through spiritual growth and transformation.
