Psalms 19:1-6 Does it really say Equinox?

Psalms 19:1 To the chief Musician, A Psalm of David. The Heavens declare the glory of Yah; and the firmament shows his handywork. #H7549 Firmament=what is in the firmament, the stars, firmament = the vault of Heaven.

Verse 2 Day unto day utters speech, and night unto night shows knowledge. #H1847 Knowledge=understanding, discernment. This can't be talking about the equinox because the equinox is only 2 times a year. The sun moves through the stars thought out the year in the firmament.

Verse 3 There is no speech nor language, where THEIR voice is not heard.

Verse 4 THEIR line is gone out through all the earth, and THEIR words to the end of the world. In THEM hath Yah set a TABERNACLE for the Sun.

#H168 tabernacle- tent, dwelling, covering.

Verse 5 Which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race. #H 3318 coming out= exit-go forth or proceed

Verse 6 His going forth is from the end of the heaven, and his circuit unto the ends of it: there is nothing hid from the heat of it. #H8622 circuit=coming around, a circuit of time.

In this Psalms we have King David telling us first about the firmament by using the words like, Their and Them, that is a tabernacle for the suns path through the constellations that make a circuit around the earth. The firmament shows Yah handywork. What is in the firmament but the stars! If you're tracking the suns path through the stars you will see the sun will complete the circuit yearly.

Some are saying verse 4 is talking about the equinox, it seems to me when it says Thier line has gone out it is referring to the three verses before and his handywork in the firmament, the stars. The stars are the tabernacle for the suns path from one end of the earth to the other every day and every month the sun travels through another set of stars. The suns going forth from one end of the heaven, and his circuit or path is through the stars unto the ends of the earth, and nothing is hidden from the suns heat.

They also say verse 5 is talking about the equinox which says... is as a bridegroom coming out of his chamber, as strong man to run a race. That would be the circuit of the stars the sun has completed and starts over for a new year and is marked by the stars not the equinox. The Equinox is marked by a straight line on earth and this Psalms is telling us of events in the firmament, the sun and stars.
