Seventy is the sum of our years, or eighty, if we are strong; Most of them are sorrow and toil; they pass quickly, we are all but gone. (Ps. 90:10, NAB)I always pause when these lines from the nineteeth psalm come up in the Breviary. The Grail Translation (which is used by the official text of the Liturgy of the Hours) translates the second half of the first sentence as: "and most of these are emptiness and pain."
Teach us to count our days aright, that we may gain wisdom of heart. Relent, O LORD! How long? Have pity on your servants! Fill us at daybreak with your love, that all our days we may sing for joy.
