What does Liora mean?
Modern Hebrew, the feminine of Lior: li 'for me / my' + or 'light,' hence 'my light' or 'light for me.' A coined given name rather than a biblical one, built transparently from everyday Hebrew words.
What does Yael mean?
From Hebrew ya'el, 'ibex' — a nimble, sure-footed wild mountain goat. The same name as the heroine Jael, who killed Sisera (Judges 4-5). A concrete noun; the 'strength of God' gloss seen on some sites is not the standard derivation.
