Which Tehillim chapters for healing
One custom is to say set chapters for healing, then verses by the letters of the sick person’s name. The Tehillim page has a healing mode. You can read a daily cycle, a single chapter, or healing mode by name. Every chapter also has its own URL, for example Tehillim chapter 23. After Tehillim you can move to a memorial order when it is for remembrance.
Can I open one chapter?
Yes. Every chapter has a public URL.
