Commentary for Psalms 2:12

Arm yourselves with purity Arm yourselves with purity of the heart. Some explain נשקו as garnimont in Old French, equipping. (This is from the verb, garnir. Garnimont means to provide, as in Gen. 41:40). Menachem (p. 179) interprets it as an expression of desire, as (in Gen. 3:16): “Your longing (תשוקתך) shall be for your husband.”

Kiss the son: – as (in the verse) "and he kissed all his brethren" (Gen. 45:15). And (the word) בר is the same as בן; and so "What, my son (בני)? "; and "what, O son (בר) of my womb?" (Prov.xxxi. 2). Or it may be interpreted by "the pure (ברי) of heart" (Ps. 73:1). If its meaning is "son," this will be its interpretation: Kiss this son whom God has called "son," as He says (above): Thou art My son. And the command is Kiss, because it is the custom for a servant to kiss the hand of the master. And if its meaning is "pure," its interpretation is, "What have I to do with you, for I am pure in heart and there is no wickedness in me that ye should come and fight against me? Your duty is to kiss me and to confess that I am king by the command of God." And בר may also be fittingly interpreted from (the verse) "Choose (ברו) you a man for you" (1 Sam. 17:8), upon the analogy of "Saul the chosen of the Lord" (2 Sam. 21:6).
