Komentaryong Sumisipi para sa Mga Awit 119:90

“The heavens” – with the definite article, to indicate that that it’s speaking of those [heavens] which are visible, and [“heavens”] are always plural. And it's possible that it means, "its domain" – the domain of each one. The meaning of “heavens” is heights and elevation, and thus it is in Arabic, which is primarily based on the Holy Tongue. There are also “heavens of heavens”, but there is no singular form, like rechayim [“millstones”] and tzohorayim [“afternoon”]. People of stature will understand these secrets. Now the Ga’on says that the earth is like a point, and the heavens are like a thread encompassing it, and after these two were created, were everything within them [created], like water and fire. Others have said that the water was included with the earth, and the wind with the heavens. According to my opinion, these heavens and earth are [identical to] the firmament and the dry land, for only one things was created on each day: on the first day, light; on the second day, the firmament; on the third day, plants; on the fourth day, the luminaries, of the fifth day, and on the sixth day, the living things. The psalm mentioned [above] bears witness. And it’s impossible for the line which surrounds to precede the point, or for the point to precede the line, so therefore did they say that the heavens and the earth were created simultaneously. Bearing witness is “I call to them, they stand up together” – Isaiah 48:13. Yet this proof is not [sufficiently] clear, for this is not the explanation of the verse, for how can He say “to them” when they are not!? And how can He call it tohu? Rather, its meaning is “I created them”, and at the time I call to them, they will both stand up before Me like servants to do My will”, as in “Your word is standing in the heavens” – Psalms 119:89. And afterwards he mentioned the earth, afterwards stating that both will arise to execute judgment as He commands them.
