Changing English text on Devotepress Pro

Hi there, I have an issue for our French language website sola.org concerning some of the text. I was able to change the "Continue Reading" and "Search" text using the customizer, but I do not know how to change the following text: 1) When displaying posts on the homepage the title "Blog" appear with "From the Blog" underneath. How do I edit these? 2) At the bottom of the page, the pagination is set to numeric. I'm concerned with the "Next" text that appears on the last link. Thank you
