The Translation of Silence in Psalm 65

There is a word that I have stumbled across in the Hebrew. It appears in Psalm 62, for God alone, my soul waits in silence. In Psalm 65, it's like the first verse. And what's the word? Do you, am I Y-A-H, do mea? Would that be how it would be? How is it translated in 65? Well, different translations render it differently.
