The tetragrammaton, the four-letter Hebrew name of God that nobody really knows for sure how to pronounce or what it means, is translated in Exodus as "I AM". Hebrew is a phonetic language, meaning each letter stands for a sound, just like English. However, Hebrew can also be an ideographic language like Chinese or ancient Egyptian hieroglyphs, where each symbol stands for an idea or a whole word. This ideographic perspective of Hebrew isn't used much anymore, but it's valid. Using this, the tetragrammaton, יהוה (the LORD), means: "Behold, the hand. Behold, the nail."
