The Book of Psalms is long, but not the longest book of the Bible. With 150 psalms and just over thirty thousand words, it ranks third, behind Jeremiah and Genesis.
The psalms were written over a roughly thousand year span. That means some are separated by centuries, shaped by different political crises, exiles, rebuildings, and fresh hopes. The book holds all of that together without ironing out the differences.
Some psalms were meant to be sung, loudly and publicly. In ancient Jewish worship they were chanted or sung with instruments. Early Christians kept singing them too. Over time, Christian monks began singing all 150 on a regular cycle.
The range of psalms we find in the book is wide. Some psalms bless enemies; others ask God to deal with them violently. One psalm is only two verses long, while another runs for pages, suggesting God is not picky about prayer length.
Interestingly, Jesus quoted the psalms more than any other Hebrew scripture. When we pray or sing them today, we step into a long tradition, trusting our voices still belong there.
