"Chapter 5—John Wycliffe Before the Reformation there were at times but very few copies of the Bible in existence, but God had not suffered His word to be wholly destroyed. Its truths were not to be forever hidden. He could as easily unchain the words of life as He could open prison doors and unbolt iron gates to set His servants free. In the different countries of Europe men were moved by the Spirit of God to search for the truth as for hid treasures. Providentially guided to the Holy Scriptures, they studied the sacred pages with intense interest. They were willing to accept the light at any cost to themselves. Though they did not see all things clearly, they were enabled to perceive many long-buried truths. As Heaven-sent messengers they went forth, rending asunder the chains of error and superstition, and calling upon those who had been so long enslaved, to arise and assert their liberty. GC 79"
"To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house."
The EGW passage directly alludes to Isaiah 42:7, using similar imagery of unchaining words of life and freeing prisoners, clearly connecting Wycliffe's work with the prophetic role of liberating people from spiritual darkness.
"Except among the Waldenses, the word of God had for ages been locked up in languages known only to the learned; but the time had come for the Scriptures to be translated and given to the people of different lands in their native tongue. The world had passed its midnight. The hours of darkness were wearing away, and in many lands appeared tokens of the coming dawn. GC 79.2"
"For, behold, the darkness shall cover the earth, and gross darkness the people: but the Lord shall arise upon thee, and his glory shall be seen upon thee."
Both passages use the imagery of darkness and light to represent spiritual ignorance and the coming of truth/revelation. The parallel is strong and relevant to the context.
"But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased."
The EGW passage echoes the theme of Daniel 12:4 regarding the sealing up of the words until the time of the end, and the increase of knowledge. While not a direct quote, the idea of the Bible being 'locked up' and the 'coming dawn' of understanding aligns with the prophecy.
