It's probably too late for this, but I'll post anyway.
This is the Estrangelo font of Aramaic, which is the oldest. I actually Like the Chaldean font better, but I can't seem to get it working right on my computer.
ܚܝܠܐ ܡܢ ܡܫܝܚܐ(khayla men msheekha)
Strength through Christ. (Literally: strength from Christ)
Just in case you want it other ways:
ܚܝܠܐ ܡܢ ܝܫܘܥkhayla men yeshua (sometimes pronounced eesho)
Strength through Jesus.
ܚܝܠܐ ܡܢ ܝܫܘܥ ܡܫܝܚܐ(khayla men yeshua (or eesho) msheekha)
Strength through Jesus Christ.
NOTE: The "kh" is pronounced like the Scottish "ch" in loch or the German pronunciation of "ch" in the name Bach. The "ay" in khayla is pronounced like the "ay" in day.
I am just a beginner, so before you get inked, it would be better to verify this information with an expert.
