- Book of Exodus (Wikipedia)
The Book of Exodus (from Ancient Greek: Ἔξοδος, romanized: Éxodos; Biblical Hebrew: שְׁמוֹת Šəmōṯ, ‘Names’; Latin: Liber Exodus) is the second book of the Bible. It is a narrative of the Exodus, the origin myth of the Israelites leaving slavery in Biblical Egypt through the strength of their deity named Yahweh, who according to the story chose them as his people. The Israelites then journey with the legendary prophet Moses to Mount Sinai, where Yahweh gives the 10 commandments and they enter into a covenant with Yahweh, who promises to make them a “holy nation, and a kingdom of priests” on condition of their faithfulness. He gives them their laws and instructions to build the Tabernacle, the means by which he will come from heaven and dwell with them and lead them in a holy war to conquer Canaan (the “Promised Land”), which has earlier, according to the myth of Genesis, been promised to the “seed” of Abraham, the legendary patriarch of the Israelites.

- A-type main-sequence star (Wikipedia)
An A-type main-sequence star (AV) or A dwarf star is a main-sequence (hydrogen burning) star of spectral type A and luminosity class V (five). These stars have spectra defined by strong hydrogen Balmer absorption lines. They measure between 1.4 and 2.1 solar masses (M☉) and have surface temperatures between 7,600 and 10,000 K. Bright and nearby examples are Altair (A7), Sirius A (A1), and Vega (A0). A-type stars do not have convective zones and thus are not expected to harbor magnetic dynamos. As a consequence, because they do not have strong stellar winds, they lack a means to generate X-ray emissions.
