Joel 2:15 In-Context

13 And rend your heart, and not your garments, And turn back unto Jehovah your God, For gracious and merciful [is] He, Slow to anger, and abundant in kindness, And He hath repented concerning the evil.

14 Who knoweth -- He doth turn back, Yea -- He hath repented, And He hath left behind Him a blessing, A present and libation of Jehovah your God?

15 Blow ye a trumpet in Zion, Sanctify a fast -- proclaim a restraint.

16 Gather the people, sanctify an assembly, Assemble the aged, Gather infants and sucklings of the breasts, Go out let a bridegroom from his inner chamber, And a bride out of her closet.

17 Between the porch and the altar weep let the priests, ministrants of Jehovah, And let them say: `Have pity, O Jehovah, on Thy people, And give not Thy inheritance to reproach, To the ruling over them of nations, Why do they say among peoples, Where [is] their God?'
