Two Letters, One Picture
Hebrew letters began as small pictures, and each picture carried a meaning. The word for mountain, har (הַר, H2022), is built from only two of them: hey and resh. Read as pictures, the word paints a man with his arms raised, standing at the head.
Hey (ה): The Raised Arms
The hey was drawn as a man with both arms lifted high. It is the letter of pointing and showing, the sound that opens the word "behold" (hinneh). It says: look at this. When Pilate brought Yahushua out to the crowd, he said exactly that, "Behold the man!" (John 19:5).
Resh (ר): The Head
The resh was drawn as a head. It stands at the front of rosh (H7218), the word for head, top, and first. When Moses went up to pray over the battle, he stood on "the top of the hill" (Exodus 17:9), the rosh of the hill. Yahushua was carried out to Golgotha, "the place of a skull" (John 19:17), the place of the head.
The Letters Acted Out
At Rephidim, while Moses held his hands up, Israel prevailed; when they dropped, Amalek prevailed (Exodus 17:11). Aaron and Hur stood one on each side and held his arms up until dusk (Exodus 17:12). A man with arms raised, standing at the head, one on either side: hey over resh. Centuries later Yahushua hung on the tree at the place of the head, arms stretched out, with "two other with him, on either side one" (John 19:18), and through it Yahuah was "triumphing over them" (Colossians 2:15). The two letters drew the picture, Moses acted it out, and the tree fulfilled it.
Behold Again
The hey still speaks at the end. "Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him" (Revelation 1:7).
