Subtle Heldenberg.

cf. Psalm 18.26-27:
עִם-חָסִיד תִּתְחַסָּד; עִם-גְּבַר תָּמִים, תִּתַּמָּם
עִם-נָבָר תִּתְבָּרָר; וְעִם-עִקֵּשׁ, תִּתְפַּתָּל

With the merciful you are merciful,
With the upright man you are upright;
With the pure you are pure;
And with the perverse--you are subtle.

This translation, stripped of the Thou Shewest Thyselves of the JPS 1917, was Steve Reich's text for the third movement of his Tehillim--by far the better recording of that work, by the way.
