Translation:

For the blind see 4.18.

Maimed, or, ‘mutilated,’ covering an area of reference in which lame (see 7.22) is included; also rendered, ‘having a bodily defect’ (Javanese), ‘deformed’ (Toraja-Sa’dan), ‘missing a limb’ (Balinese).

(V. 14) You will be blessed, or, ‘happy,’ see 1.45.

Because they cannot repay you, or, ‘they cannot do-to you things that you have done-to them’ (Kituba), expresses the reason of the preceding statement in negative terms, the next clause does the same in positive terms: what the poor etc. are not able to do now God will do in a more splendid way at the resurrection; hence, the two clauses are sometimes more closely connected, e.g. ‘because they cannot repay you, but you will be repaid (cf. New English Bible, Phillips, Malay, Batak Toba), or, but God will repay you.’ Since at its third occurrence to repay has another nuance of meaning, pointing beyond the human sphere, a different rendering may be required.

At the resurrection of the just, or, ‘when the righteous arise from death’ (Thai 1967) ‘when those people who righteous they-will live-up (i.e. return to life)’ (Trukese, Pohnpeian). The just, or, ‘the just/righteous ones,’ or, sometimes, ‘the righteous dead ones,’ ‘the dead ones that have been righteous’; and cf. the references on “righteous” in 1.6.
