Hastings' Dictionary of the Bible [3]

Estate . ‘State’ and ‘estate’ occur in AV [Note: Authorized Version.] almost an equal number of times, and with the same meaning. Cf.   Colossians 4:7 ‘All my state shall Tychicus declare unto you,’ with the next verse, ‘that he might know your estate.’ In   Acts 22:5 ‘all the estate of the elders’ (Gr. ‘all the presbytery’) means all the members of the Sanhedrin. The pl. occurs in the Pref. to AV [Note: Authorized Version.] , and in   Ezekiel 36:11 ‘I will settle you after your old estates,’ i.e . according to your former position in life, The heading of   Psalms 37:1-40 is ‘David persuadeth to patience and confidence in God, by the different estate of the godly and the wicked.’

International Standard Bible Encyclopedia [4]

es - tāt ´: While the King James Version uses both "estate" and "state" with the meaning of "condition," the American Standard Revised Version distinguishes, using "state" for the idea of condition, "estate" for position; and replaces "estate" of the King James Version by more definite expressions in many cases. Compare  Colossians 4:7 the King James Version, "All my state shall Tychicus declare unto you," but   James 4:8 , the King James Version "might know your estate" the Revised Version (British and American) "may know our state";  Luke 1:48 the King James Version and the Revised Version (British and American) "the low estate" (of the Lord's hand-maiden);   Mark 6:21 , the King James Version "chief estates" the Revised Version (British and American) "chief men";  Daniel 11:7 ,  Daniel 11:20 ,  Daniel 11:21 ,  Daniel 11:38 , the King James Version "his estate," the Revised Version (British and American) "his place," both with margin "his office."
