Answer:
Lincoln's "Gettysburg Address"
Step-by-step explanation:
As the Vice President at the time, the future 36th President of the US, Lyndon B. Johnson, delivered a speech supporting civil rights at Gettysburg, Pennsylvania on Memorial Day, May 30, 1963. Johnson's support of the civil rights movement was significant.
The eloquent words he mentions in his speech is Abraham Lincoln's "Gettysburg Address", a speech Lincoln delivered exactly a century before Johnson's, in 1863, to celebrate the victory of the Union's armies in the Battle of Gettysburg.
