"generation": the word

In some thread earlier, I had mentioned that the use of the word 'generation' in the Bible could be in one of three ways: a specific period of time, a group of contemperaneous people, or a much vaguer classification regarding people of a particular type of any time in history. I was questioned about this last one and did not have a ready reference, so I shut up...

However during the course of our own Bible studies, Barry and I were reading some of the Psalms today and I found one of the references that would have helped in the thread before. In Psalm 26 we read,

"Who may ascend the hill of the Lord?
Who may stand in his holy place?
He who has clean hands and a pure heart,
who does not lift up his soul to an idol
or swear by what is false.
He will receive blessing from the Lord
and vindication from God his Savior.
Such is the generation of those who seek him,
who seek your face, O God of Jacob."

Hope that helps a little.
