ischus denotes strength or might, whether devoted wholly to God, supplied for service, or named in praise.

The occurrences most often place the noun in statements about strength or might belonging to God or attributed in exalted settings; it also names the full strength with which God is to be loved. In service, it is the strength God supplies, while other clauses place it alongside power, glory, wisdom, or honor.

2. Whole strength in the command to love God · common

   In Luke 10:27, Mark 12:30, and Mark 12:33, the noun appears within the repeated instruction to love God with all the heart, soul, mind or understanding, and strength. The APB renders the relevant phrase as “with all your strength” or “in all your strength,” presenting it as one element of total devotion.

3. Strength supplied or possessed · occasional

In the Anselm Project Bible: The APB commonly uses “strength,” including “the strength that God supplies,” “the glory of his strength,” and “all your strength”; it also uses “might” in Revelation 7:12. These renderings show the verse-level presentation rather than a fixed English equivalent.
