Perek 27

A couple of months ago I received an email about a young boy with a brain tumor. People were asked if they wanted to say Tehillim for the boy and I signed on for one perek. I received an email that I should say Chapter 27 - which is a famous perek that is recited in the days leading up to Yom Kippur. So, even though it is not the month of Elul, I have been reciting the perek in the merit of a speedy recovery for Yosef Simcha ben Zaka Basya.
Two sentences before the end of the chapter is the following verse.
Tehillim 27:12 Deliver me not over unto the will of mine adversaries; for false witnesses are risen up against me, and such as breathe out violence.

In Hebrew, the word "violence" is translated as "Chamas - the same word used for a movement which sends rockets across its borders into Israel.
King David knew that those who are our adversaries, who breathe violence, are also capable of bearing false witness. How many massacres has Israel been accused of? How many times have settlers been accused of starting the violence which really began from the other side?
I thought of the above verse when I read an INN article last night.

A medical intern from Majdal Shams has been identified by police as one of the people who threw rocks at IDF soldiers on the “Naksa Day“ disturbances in the Golan Heights. The suspect works at Ziv Medical Center in Tzfat (Safed).
Apparently the suspect was questioned by police and he admitted he had been at the riots "to lend medical assistance to casualties."
..."He was released, but police later acquired video footage that clearly shows the suspect hurling rocks at soldiers. He was rearrested and the investigation was reopened."

Bearing false witness and using violence are partnered once again.
Among the words in the Hippocratic Oath is the promise "and never do harm to anyone."
Dr. Mengele, and a medical intern bear false witness to these words.
And what is one supposed to do? King David offers the prescription in the closing verse of this chapter.

Kaveh el hashem,chazek vayametz libecha v'kaveh el hashem.
Wait for G-d, strengthen and encourage your heart,and wait for G-d.
