In Hebrew, I Am shares the same root letters as the infinitive, To Be. It is for that reason that spoken Hebrew omits the various tenses of the verb, for fear of accidentally speaking the name of God in vain.
One thus would say, I Mrs. Don-o, not, I am Mrs. Don-o; the verb is implicitly understood.
The name of God means I Was, Am, and Will Be, simultaneously.
Amen. Amen to His Glory! He Who is, and was, and is to come.
