Hebrews 3:8-10 Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:

AKJV_Strongs⁽ⁱ⁾

8 G4645 Harden G5216 not your G2588 hearts, G3894 as in the provocation, G2250 in the day G3986 of temptation G2048 in the wilderness:

9 G3756 When G5216 your G3962 fathers G3985 tempted G1381 me, proved G1492 me, and saw G2041 my works G5062 forty G2094 years.

10 G1352 Why G4360 I was grieved G1074 with that generation, G2036 and said, G104 They do always G4105 err G2588 in their heart; G1097 and they have not known G3598 my ways.
