🔼The name Sisera in the Bible

🔼Etymology of the name Sisera
BDB Theological Dictionary suggests that the extension -sira is common for Hittite names but gives no meaning. Fuerst's Hebrew & Chaldee lexicon to the Old Testament draws towards a foreign word meaning meditator and NOBSE Study Bible Name List reads Meditation as well.
To a Hebrew audience, however, the first part of the name Sisera may have reminded of the word סיס (sis), meaning swallow or horse (Note that some later versions of Jeremiah 8:7 use the form סיס, sis):
