Changing the "Older Posts" and "Newer Posts" buttons on the Blog Post Page to a new name

Hi, I am trying to change the text of "old post" and "new post" on the blog post page. I have found code on how to hide the text and just have the arrows. But I want to keep the text and just change what it says. 

Thank you!

What is blog page url? We can check easier

Right now I have added the code to hide all text and just keep the arrow but if you can help me change what the text says instead that would be great

Remove your code & use this code to Custom CSS box

span.next-label {
    font-size: 0;
}
span.next-label:before {
    content: "previous";
    font-size: 16px;
}
span.prev-label {
    font-size: 0;
}
span.prev-label:before {
    content: "next";
    font-size: 16px;
}
