Reader's digest did an article series back in 1970 called "I am Joe's Body" One of the installments in the series was titled "I am Joe's Man Gland" Only version I can find on line drops the subsection titles, and merely lists Joe's testis:
I am Joe's left testis. Compared to other glands, I am not bad- looking at all: a
glistening, pink-white oval. I weigh four grams and am four centimeters long, two centimeters at my greatest diameter. My function is dual: to manufacture those
creators of life, the sperm cells; and to produce the hormone of maleness, testosterone. This chemical assists in construction of muscle, bone and other tissues. It helps shape Joe's mental attitudes as well as his body. But for it, Joe
would be soft, flabby, beardless, apathetic.
The title, its derivatives, and the attitudes expressed in the piece became a bit of a pre-internet meme.
I have no good answer for 'next night', but I commend to you 'yestreen' -- a word meaning 'yesterday's evening', which was still in (possibly affected) use in the 19th century. That may be Scottish; a more English version is 'yester-even'. See also 'forenight'. The first use of 'yestreen' noted in the OED was 1400 -- not necessarily Old English, but definitely unlike modern English.
Also, you may be pleased to know the existence of 'Saturnight', 'Sunnight', 'Tuesnight', 'Wednesnight', 'Thurseven' and 'Frinight'. In all cases, these referred to the night before the corresponding day. They are all labelled Old English -- so, earlier than 1400.
It might not copy perfectly, but here is the OED's earliest noted use of 'Thurseven':
Prose Charm: Against Elf-Sickness (Royal 12 D.xvii) in G. Storms Anglo-Saxon Magic (1948) 222 Gang on þunres æfen, þonne sunne on setle sie, þær þu wite elenan standan.
I can't help you with a translation.
A pleasing word meaning 'the end of the night, just before daybreak' is 'ughten', but the etymology isn't clear to me. It's in Beowulf (~1000AD) and fitted into the Germanic/Saxon/Old-English mishmash at the time.
Straying into invention, I suggest 'to-fall' -- a word meaning 'beginning of night', whose examples in the Oxford English Dictionary (which I've used for all the words listed) all look to the future. It was first used in 1425, though not in the meaning we're discussing.
