עִם־חָסִיד תִּתְחַסָּד עִם־גִּבּוֹר תָּמִים תִּתַּמָּם׃
With a kind person, You are kind. With a person strong in innocence, You are innocent. Shmuel 2:22:26
תָּמִים could also be translated as whole, or "wholehearted", or simple.
I would like to know how Hashem can act תָּמִים, or rather how could He not appear תָּמִים to someone?
I would like to know why the first (חָסִיד) isn't diluted (or perhaps concentrated?) with the word גִּבּוֹר?
