EASTON’S BIBLE DICTIONARY (1897 EDITION)
Anchor – From Acts 27:29, 30, 40, it would appear that the Roman vessels carried several anchors, which were attached to the stern as well as to the prow.
The Roman anchor, like the modern one, had two teeth or flukes.
In Heb. 6:19 the word is used metaphorically for that which supports or keeps one steadfast in the time of trial or of doubt.
It is an emblem of hope.
“If you fear, Put all your trust in God: that anchor holds.”
