Yahoo and Yahveh
In biblical times, it was common wisdom that leaders needed two special qualities known as "Urim v'Thummim."
Scholars have puzzled over the meaning of those two Hebrew words, which literally mean "Lights and Perfections."
I reckon that a modern interpretation would be that Urim means mindfulness, brilliance, insight, awareness.
Thummim is a tad more challenging to interpret. I reckon that it means empathy, compassion, mercy, heart, beneficence.
A colleague of mine likes to translate "Urim v'Thummim" as HeartMind.
Did Marissa Mayer stumble in her ability to guide her minions with Urim v'Thummim in her mind and in her heart?
