'Dost' in the Bible

Thou dost call as at a day of appointment, My fears from round about, And there hath not been in the day of the anger of Jehovah, An escaped and remaining one, They whom I stretched out and nourished, My enemy hath consumed!

Thou hast covered Thyself with anger, And dost pursue us; Thou hast slain -- Thou hast not pitied.

Offscouring and refuse Thou dost make us In the midst of the peoples.

You, O Lord, rule forever;Your throne is from generation to generation.

Wherefore dost thou forget us for ever, and forsake us so long time?
