Pentecost +23 - Year B
This sounds more like a Proverb that has lost its way and ended up in the Psalms. It also is of a very masculine ethos, more didactic than hopeful. The contrast with the other pericopes is pretty stark.
The widow seems to acknowledge G*D, it is the context of the event; in Ruth’s birthing of Obed, G*D’s presence clarifies actions leading up to that event; and Hebrews speaks not to meeting enemies in the gate and prevailing, but an eager waiting for anticipated saving. These speak to an openness to a better future and are different than the psalmist claiming of G*D and having "victory" be a certain result.
Perhaps this paraphrase by Jim Taylor will help see this psalm in light of the other passages.
1 The road of life takes many tricky turns;
you never know what crisis waits around the corner.
2 Each day has only 24 hours;
You cannot accomplish any more by burning candles at both ends;
You will only burn yourself out.
But God knows what you can do, and God will give you the strength you need.
3 God gives family and friends to sustain us when we weaken;
4 They are our insurance against the future.
5 Treat everyone as a friend,
and you will never lack for support when you need it.
