Hebrew is the language used throughout most of the Old Testament/Hebrew Bible. It was written from right to left and includes 22 letters.
The oldest written form of Hebrew did not include any vowels, only 22 consonants. Eventually, a written vowel system was developed that could be incorporated into the Hebrew Bible without interfering with the order or appearance of the consonants. To an everyday English reader, this vowel system looks like dots and dashes usually written below, but sometimes above, the consonants.
