You must have googled the same things I did. NO WHERE do those versus tell us TO PRAY TO THEM!
In Revelation 19:10...At that I fell down before his feet to worship him. But he tells me: “Be careful! Do not do that! All I am is a fellow slave of you and of your brothers who have the work of witnessing to Jesus. Worship God; for the bearing witness to Jesus is what inspires prophesying.
Neither word "pray" nor the word "prayer" appear in this verse. Prayer and worship are not the same thing and one can happen without the other.
You are constrained by the English language and your understanding of the subject. You are confusing the act of prayer with the act of worship. These are clearly not the same so you cannot continue to use them interchangeably. Prayer is the application of the mind to Divine things, not merely to acquire a knowledge of them but to make use of such knowledge as a means of union with God. This may be done by acts of praise and thanksgiving, but petition is the principal act of prayer. The words used to express it in Scripture are: to call up (Genesis 4:26); to intercede (Job 22:10); to mediate (Isaiah 53:10); to consult (1 Samuel 28:6); to beseech (Exodus 32:11); and, very commonly, to cry out to.
Additionally, both worship and veneration are not absolutely constrained by a finite list of thou shalls and thou shall nots. Because one is not specifically commanded to pray via a saint does not prohibit it.
