I heard this from Rav Aaharon Yaskil
Here
is something very interesting. The sum total of the numbers of chapters
of Tihillim in Tikun Haklali are the words "Iron dome" in Hebrew "kipa
barzel"
This is inclusive repair or if you will total spiritual repair
given to us by Rebbe Nachman of Breslov. They are the following perakim
of Tehillim, verses of Psalms 16+32+ 41+ 42+ 59+ 77+ 90+ 105+ 137+
150= 749.
Which equals 749 the sum total gematria of the words
"kipa barzel" exactly!
Our Iron dome is total Ruchniut! It is totally
spiritual! For our weapons are not physical.
This is our protection! Please say them for Am Yisrael now!
