Exodus 12:6
fourteenth <0702> [fourteenth.]
whole <03605> [the whole.]
around sundown <06153 0996> [in the evening. Heb. between the two evenings.]
The Jews divided the day into morning and evening: till the sun passed the meridian, all was morning or forenoon; after that, all was evening or afternoon. Their first evening began just after twelve o'clock, and continued till sunset; their second evening began at sunset, and continued till night, i.e., during the whole time of twilight; between twelve o'clock, therefore, and the termination of twilight, the passover was to be offered. See Parallel Passages.
