I will not take the time to go through all of them but, the Old Testament has many examples of saints who fell to the ground. In Genesis 15:12-18 for one is when Abraham was put to sleep horror and great darkness fell upon him, but it was not pleasant. This was a special event signifying God’s covenant with Abraham as God told about his offspring’s future. This act was not repeated for any of his descendents. Notice the passage indicates that the experience was not enjoyable. Genesis 17:3 Abraham falls on his face, but this does not describe an involuntary act of being slain in the Spirit as some claim. Abraham fell face forward toward the ground on his own accord, in reverence, in an act of fully conscious worship.
Many fell backwards in Scripture, but it was not a blessing! In 1 Samuel 4:18: Eli fell off his seat backwards on hearing of the death of his sons and the capture of the Ark and he died. Isaiah 28:13 the prophet speaks of God’s Word sent to refresh, but if not heard it became a judgment “that they may go and stumble backward, and be broken.” In all these examples it is a judgment, not a blessing! In 1 Samuel 28:20 we read of Saul immediately collapsing “full length” on the ground upon hearing of his impending death from Samuel after consulting the witch of Endor.
