The title refers to God's name, written with the Hebrew characters known as the Tetragrammaton, and appears almost 7,000 times in the Old Testament. In Hebrew it is normal to write only consonants, but because of the Commandment against using God's name in vain, correct pronunciation of the name is lost. Name YHWH is preserved in texts but sometimes has added vowel marks from word Adonai, indicating that instead of YHWH one should read Adonai (Lord). English Bibles usually translate it as "Lord of Hosts," or simply as "Lord." One plausible version of OT God's name might be "Yahweh," although some use "Jehovah" instead; that stems from erroneous reading of YHWH with vowels of Adonai.
