Hebrew is an ancient language which in it's beginnings was written with what is called pictograph symbols. Each letter was a drawing of an object, like a tent, a wall or some other object, and not only had a sound, and a name, as the western alphabet has, but it also had a meaning. In the book of Isaiah, God (YHWH) said I am the “first and the last” " the "beginning and the end" .
In Greek, when Jesus made this statement written in the Greek alphabet, it was stated as the “Alpha and Omega”. In the English alphabet, it would be the “A and Z” Yet when it was expressed in the Hebrew pictograph, it was expressed as the “Aleph and the Tav”.
Aleph and Tav
Aleph and Tav, being the first and the last letters of the pictograph in Hebrew were expressed, or drawn as an Ox head, also meaning strength, and a shape much like a cross. (Two crossed sticks which are used as a marker. AHRC)
It is interesting to note that cattle were used as sacrifices to Jehovah, and at the time that Jesus Christ, who is “God with us” arrived on earth, the method of execution was a cross. An Aleph, an ox, or sacrifice, on a tav, or a cross. Even before the LORD had a body, He was speaking of Himself as the sacrifice that would pay for mankind, the sacrifice on (Calvary’s) cross.
This reminds me of the scripture of Abraham talking to His son, Isaac. And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering? And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together. Genesis 22:7 & 8
YHWH did provide Himself a sacrifice on Calvary.
