The Hebrew letter Resh [ר] signifies poverty or need. Scholars say it looks like a man bent over. It’s appropriate, then, that in these eight verses the psalmist most acutely expresses his awareness of his need and inability to help himself. If you are keeping track, he asks for help in seven different ways.
“Blessed are the poor in spirit,” said the Lord Jesus, “for theirs is the kingdom of heaven.” Significantly, resh (spiritually impoverished) transforms into rosh (head or leader) by swapping out a single vowel. There are no vowels written in the Torah, so this ambiguity is part of the package. The last shall be first.
