🔼The name Alvan in the Bible
The name Alvan occurs only once in the Bible. In Genesis 36:23 he is listed among the sons of Shobal, son of Seir the Horite. In 1 Chronicles 1:40 this man is called עלין (Alian), which is only slightly different.
The same alternation in spelling occurs with the name of Alvan's brother Shepho/Shephi.
🔼Etymology of the name Alvan
The name Alvan comes from the following root group, but scholars don't agree which root exactly:
Our name seems to be constructed of the word על and the familiar extension ון, which personifies or localizes the root. Alvan means על-Man.
For a meaning of the name Alvan, NOBSE Study Bible Name List takes the על-part from the root עלה ('ala), meaning to ascend, and reads Tall. Jones' Dictionary of Old Testament Proper Names sees connections with the verb עול ('ul), meaning to be unjust, and reads Unrighteous. BDB Theological Dictionary doesn't translate this name, but does list it under the root עלה ('ala).
