HARD.Besides other meanings which are still in use, hard sometimes means close: Jdg_9:52 And Abimelech
went hard unto the door of the tower to burn it with fire; Psa_63:8 My soul followeth hard after thee; Act_18:7 Justus
whose house joined hard to the synagogue. Cf. Job_17:1 in Coverdale, I am harde at deathes dore.
Hardiness is used in Jdt_16:10 for courage: the Medes were daunted at her hardiness (RV [Note: Revised Version.] boldness).
Hardly means either harshly, as Gen_16:5 Sarai dealt hardly with her, or with difficulty, as Exo_13:15 Pharaoh would hardly let us go; Mat_19:23 a rich man shall hardly enter into the kingdom of heaven; Luk_9:39 bruising him, hardly departeth from him; Act_27:8 And, hardly passing it, came unto a place which is called The fair havens. So Adams (2Pe_1:4) He that hath done evil once, shall more hardly resist it at the next assault.
Hardness for modern hardship occurs in 2Ti_2:3 endure hardness as a good soldier. Cf. Shakespeare, Cymb. iii. vi. 21
Hardness ever
Of hardiness is mother.
