day´-star`

(dā´stär`)
n.1.The morning star; the star which ushers in the day; - usually the planet Venus, when seen before and just after sunrise.A dark place, until the day dawn, and the day-star arise in your hearts.- 2 Peter i. 19.
2.The sun, as the orb of day.So sinks the day-star in the ocean bed,
And yet anon repairs his drooping head,
And tricks his beams, and with new-spangled ore
Flames in the forehead of the morning sky.- Milton.
